Xfinity does not explain their promotions with employees

Decided to take advantage of the free mobile line by bundling with my internet service. I asked over the phone with someone name "Rain" who said he was putting a note in my account that the free mobile line included both the Mobile Select and Mobile Plus plans. I knew both plans had different pricing and took his word.

At the Store front, with my wife, we worked with an associate to get a new phone, trade in her old one, and start the phone service. (I wont even get into the other associate that tried to break my wife's trade in right in front of us. (couldn't bare to believe the complimentary phone chargers scattered around the store were weak chargers. Tried to tell me her phone had a dead battery after it failed to charge fast enough to stay powered on during the extensive file transfer. The associate that was helping us originally took it upon herself to use a different charger (that worked) to keep the phone powered correctly. )

I asked about the free mobile line. I asked if there would be a price associated with the Plus vs the Select. She said no. We will only be billed for the new phone. As we continued through the process I asked, When the free year of service expires, what will my bill be for service. She said $30 per month. I asked which plan that was and she said the Plus. She said the Select plan would be $20 per month. I asked if I could change plans to the cheaper one after the on free mobile line expires and she said yes. Over and over and over again I was told "The free mobile line covers both the Plus plan and the Select Plan. 

Less then 48 hours later I have a bill for August. $33. I look into it and it shows the Plus plan costing $55 (higher than everything Ive been told to this point) With a $10 credit for bundling internet and mobile and a $30 credit for the free line. Leading to $15 remaining balance plus the monthly cost of the new phone. I want to know why. Why cant your employees be upfront about billing? Why cant they show my bill while in store? Is this misunderstanding as simple as I failed to ask for my formal estimated monthly bill in-store? Where the discrepancy is apparent to everyone?

So, I proceed to online xfinity support. I tell them what happened and they tell me "This is your bill and here is the breakdown". I know the breakdown. I wouldnt be talking with you had I not known. We go in circles for far too long when I decide to have my plan changed to the select plan so I can actually feel like I have a free phone plan and will only pay for the balance on my new phone. They send me the changed plan to sign off on it. The select plan is $40 not $30 so my Credits zero it out. Sounds like it worked out. Oh look here. A NEW Charge. "Phone insurance: $15" ... So all of this back and fourth to end up with the same bill as before I spent all this time. All I really needed was "We are sorry for not giving you correct information on pricing and billing." That is all a man like me needs. Ill pay the $180 a year for phone service. Its still cheaper than what my wife was paying before. Do Better! One person at any point before I signed could have said: "You will pay $18 a month for your phone and $15 for your service using this promotion." Instead I was given an Ipad with a box that says sign here. Where's the agreement for me to read before signing? Where's the billing breakdown? Where's the fine print? Nothing, just a box that says "You agree to use this signature for xfinity documentation?" 

Rant over. I hope everyone who reads this makes absolutely clear their understanding of Xfinity and their promotions before making decisions. Getting surprise bills isnt fun for anyone.
