Bad Sales with lies

I have been having troubles with VODACOM service, how i wish i had money and cancel all my contracts. I have been a client for more than 19 years but now i feel so helpless. In november my debit order was 1265.95, a lady called me for un upgrade. she said to me they have been receiving complaints about a samsung phone that i upgraded to in September. I said to her i am not interested why did they sell me a phone that they know it has problems? She said they did not know that and i said to her i am currently paying for a phone that is sitting in a drawer. She said VODACOM would like to offer me 2 blue thooth for free. i asked her more than once if this will affect my monthly payments she said no. Then December my debit order was 1408.94 i called and the lady on the phone said it is because of the speakers that my debit order went high. I told her they must pull the recording as the lady that gave me speakers said their free. They came and collected the speakers but now my january debit is 1364.94. They said to me this month the debit order will go back to 1265.95 which was a lie. When i called the customer care i was sent from pillar to post. Can someone if there is someone at VODA****. resolve this
