Telkom not answering my questions

Telkom mobile is giving me problems. Firstly my home address on my account is wrong. Secondly I am debited a lot of money. Today I went to Menlyn to inquire and they told me that I am given airtime and in order not to be debited a lot of money I should not use it. I was paying R180 from the start of the contract but now I am paying around R1500. I even called the landline last week and the lady who was helping me told me that she is escalating my problem even now I'm still waiting for them to call and help me...I asked so many questions but honestly I was not answered...I even paid the amount I was told I am owing but now I feel I was ****med...I am so frustrated
