Worst customer experience ever! BBB and FTC are my next call!

Where do I begin. Well I've been a loyal custy for years now. But recently I've been over charged upwards of $200 over the last 6 months. I first spoke to someone about it in September. Thought it was settled now here I am having not paid my bill over the last few months solely due to the fact that you guys are over charging my account by $25-$65 each month. Now my service is off which is fine for now on day 16. Now during the first 13 days I recieve calls from you guys 3-5 times a day maybe more while I was working working(I work alot). Then finally on day 13 I get a chance to call yall back. Not to pay the bill... no, because I'm owed around 200 bucks. So,ill try to finish this up quickly I've spent around 3 hours per day for the last 3 days trying to explain the situation and to get ahold of a supervisor because the [Edited: Inflammatory] couldn't help after having to explain it to 2 people over and 2hour conversation. So finally I get on hold for a supervisor which turned out being 45 minutes before the last person I was on the phone with finally takes a call back number which was fine all Good at first. About an hour later you call and hang up right away. 2 seconds thats what I was worth in that moment. So I had to call back right? So I did and I wait another 45 minutes or so after having to re explain myself to 2 more people all over again because they must must must know my problem to see if they can handle it when I know they cannot(very annoying). After waiting another 45 minutes the last person I talked to said it was to late took a call back number and says they'd call the next day. Again ok cool whatever I'm getting really angry at this point anyways probably better that way. The next morning at 4AM my time I get a call... 1 call... all day long of course I was asleep I have work at 6 am... remember back the first 13 days when yall wanted my money and called me almost ever hour of the whole day until around 5pm my time when I get off work. Now over these last few days I got that one phone call at 4am... so I get off work I call again but thus time is like 8:30pm xfinity time so I'm not gonna get a hold of no supervisor at that time but I try and I wait on the line another 45 minutes for the last person I talked to take a call back number this time asked me what time was good to call back.. YAY! maybe just maybe I'll finally get this dealt with right i told her 10am my time which is 7 their time i guess?.... guess what? [Edited: Inflammatory], 10AM [Edited: Inflammatory]. Matter of fact no phone call all day. I took an early lunch for that phone call... so I get off at 5pm my time get on the phone 5:30 (8:30 your time) I call back get ahold of someone and I'm like ok straight up I'm not going through this whole conversation I've spent 3 days trying to do please just connect me to a supervisor right away please. This time no fight no misunderstanding she says ok and puts me on hold this time for around an hour until around 6:20pm... [Edited: Inflammatory] Is this how yall value and respect me and my time as your customer commitment states? First yall bait and swhich me on an upgraded gateway that's actually a downgraded one when I get it and after I send it back yall charge me 65 extra dollars in fee on top of my 65 dollar bill? On top of that raise my bill monthly from 65 to 91 and then on top of it charge me 25 or 35 dollar in returned bank funds over the next 2-3 months which only happened because yall are over charging me by 25 bucks? Up until all this bait and switch tactic i paid my bill on time with no problems or late payment. Not once in years. Now I'm to a point where if I don't get what I deserve as a very very loyal and long time customer I'm going to contact the BBB(Better business) and also the FTC(Fed Trade Commissions) for what is a blatant bait switch) and I bet I'm not the only one. You tell me... please someone tell me what else I'm supposed to do or how you would feel? Still sitting her without an internet connection having had to pay $90 for some prepaid hotspot. Which is also still an ATT hotspot may I add. Talk about loyalty... well not much longer when that loyalty is no longer. Sorry for the long post but I'm left no choice. Look forward to someone contacting me asap

Thank for your time!
