AT&T cellular service about 3 years ago I bought a $400 AT&T smartphone which back then they weren't really too smart. and I picked the lowest data plan they had because I'm disabled and I'm homebound and they told me that it wouldn't cost me nothing search the internet using my router. well the first month's bill was over $1,000.  Nationwide

about 3 years ago I bought a $400 AT&T smartphone which back then they weren't really too smart. and I picked the lowest data plan they had because I'm disabled and I'm homebound and they told me that it wouldn't cost me nothing search the internet using my router. well the first month's bill was over $1,000. I called him we argue back and forth they're trying to tell me that I was streaming videos or something like that. even one of the technicians that work there told it would be impossible to use within one month the amount of data they were charging me for. I worked for AT&T as a computer engineer I know what I'm doing so I totally disabled than AT&T network protocol so that way it would be impossible for me to use their data to search the internet. and on top of that I never searched the internet at all the second month. but yet I got another bill and this one is for $1,200. I contacted the FCC and filed a complaint against them and got nowhere. till this day I still have a 1200 dollar debt on my credit history for that BS.
