I had a really bad experience (and still do) when I switched from grandfathered to the new unlimited. I do wish I could go back, and now I'm so unhappy I am willing to leave to any other carrier. This is after having been at AT&T Wireless for over 20 years. I've been there so long my first cell phone was one of those analog ones with the pull out antenna. Heck, I've been there so long I remember when it was called McCaw Wireless.
I don't want to get into a long rant, but probably will.
Basically between the loss of FAN, increased line items for DTV/HBO, and increased fees I ended up much, much more per month. The DTV stuff you have to pay for, but then is supposed to be credited back. Except I never got credited back. When I complained at the store he said it could take a few months for the credit to start kicking in. Wow, that was lie. I waited 4 months and it never kicked in.
It turns out I don't like DTV anyway, it's live with commercials and the user interface is the worst I've seen of any TV service. I'm not really into that. When I tried to cancel DTV, I could not, and still cannot cancel it. They have no record of me being a customer, and cannot find me based of of my name, address, or telephone number. They ask for my account number which I cannot give because it is electronic billing, so I've never received a letter with an account number on it. In fact the only communication I have from DTV is the initial welcome email, which does not contain an account number.
So I called my credit card company and told them I'm unable to cancel after two tries through DTV customer support, and I wanted to deny all future charges from them. Unfortunately VISA cannot do that in their system, they can only "contest" charges. So they've done that. I'm not really sure how that's going to work out. Maybe I will have to contest charges every single month until DTV gives up. I am concerned that DTV will send this to a creditor or worse...ding my credit report. All because they cannot seem to find me in order to cancel me--even though they can find me every month to bill me.
I guess this is really a DTV rant more than an AT&T rant, but they are the same company now.
The only positive I feel that I got out of this is that I can use tethering now, and that's been handy once or twice.
