AT-T Direct tv Charging me for service they do not provide Santa ana Nationwide

 About six months ago we moved to New town and desperately needed internet. We were approached by sales people in a Wal-Mart that said we could only have Att where we lived and we had to bundle TV and phone or we were not allowed just internet we were upset as we do not use landline or need TV. Long story short we were stuck to get internet we had to get bundle. They did credit check said everything was good and took 25$ deposit. A few days later a repair guy comes demanding 100 more after a contract was signed . Also we were told when we signed up we would get gift cards that never appeared. A month ago the internet went out and they can't fix it. However we still have to pay or they ruin our credit. We feel beyond ripped off and stuck in a 2 year contract we want out of.
