AT&T DSL Over charged DSL cost rip-off San Antonio Texas

At first, I signed up with DSL internet modem with a deal of $19.99 per month with a 1 year contract. After a few months (like 3 months), they went from $19.99 per month to $49.99 per month. From $19.99 to $49.99 per month in 3 months after 1 year deal? I contact with AT&T in regarding this and they just won't do anything at all and racking up my bill without any discount.

I let them go and found another better deal with DSL. They kept on sending bills with LATE FEE! They now threaten me for collection agency from Riverside, California. I wrote them a good, strong letter to both of them to ask to stop sending anymore billing statements. A month later, I get another bill from them, this time I marked this letter "Refused, return to sender - overcharged".

I know there are millions of people who uses AT&T for phone and Internet Modem. You all must stay away from AT&T!
