i am a mother of two kids, i am unemployed. i got a website and decided if i am going to stay to take care of my babies i nee to try and make some money. i can't afford babysiting, i listed free listing on yellow page and the next day i got a call from at&t advertising company to upgrade my listing to paying listing, i told the agent that i don' t have money to pay. he said there is a free 3 month trial in my area that i will have the option of canceling within three month. but after some days at he called me back that the three month listing is expired . i told him to cancel that i don't want to owed. but he keep calling me

back(harassing me) trying to convince me that he guarantee i will make money on my website to pay my bills and i believed him . before i know it i received my first bill which freaked me out. and i called the agent again that cancel the account i want to make sure i can pay this bill off. he keep saying i should give it more time it early. again next bill arrive not one single sale or signups o n my sites and i can't afford to pay anything. i believe the sales man was just trying to make a sale without considering anyone which is unfair and wrong.now at&t is sueing me for the unpaid bills. how are my surpose to pay that. i can bareley eat or take care of my rent .i am being harass right now. am not happy. i am always careful never want to owe money but i fell for the lies of bad business partner. am shock they will do this . i have nothing to give. am flat broke. even i called them to try to explain i have no job and they still are suing me. i have contacted a lawyer but the fee is too high am trying to find a probono lawyer. they should not be offering this kind of service. it unfair and wrong. i have to file a complain to better business bureau.what  they are doing is wrong and unfair. because they have money does not mean they can treat people like that.
