Horrible customer service

I got a gateway modem today, waited for a tech to come like they were supposed to and no one showed up--turned out the person I talked to on Monday to set it up never bothered to enter it. So, I called the phone number, the automated thing told me to activate it remotely so I did. Nothing worked. So I got on the chat and got a real person who promptly disappeared. So I called tech support to get it activated (after I'd moved my TV and dug through all the wires behind it) and had her work on it. So after 45 minutes of messing arround she says that it wouldn't activate because a tech needed to check out the internal wiring??? On a brand new modem??? So, since this was the third time and literally 6 hours of phone calls this week later, I said I wanted a supervisor to call. "I'm sorry, maam, the supervisors can't call anyone back because they're too busy taking phone calls". Just then my husband came in and said very loudly that if we have an emergency and have no phone there would be hell to pay (we still use a landline). So then she said the supervisor will call tomorrow on our house  phone--like we had just told her that the house phone wasn't working because the modem wasn't working--so she finally restarted the old modem for us for now. I'd love to be a fly on the wall tomorrow...

Anyway, this was after the cable box on my husband's big screen TV died just as the Vikings game was starting last Sunday, which really made him mad, so I was on the phone for an hour and a half then and things still didn't work. "Oh and by the way, you're paying too much so I can save you some money" so ok as long as nothing gets changed in what I have. So later went to watch something on Turner Classic Movies and it said subscription required??? Never had subscription to it as it was always included in my package. So I called back and spent another two hours on the phone just to find out that the first guy had totally cancelled what I had before and changed the stuff I had to a different package which was missing half of what I had and they couldn't change back to what I had because contract, you know....by the time I got back what I had it was going to cost me $40 more. I'm trying to figure out a way to cut the cord if I can get something that my husband can get his sports stuff on. So much for having been a customer of all the iterations before for 35+ years.....
