Telkom has turned my Bank account into a play ground

In July 2019 I went to a Telkom store in Jabulane mall and took a Huawei P30 lite contract phone which I saw on the Telkom magazine for R299 and when I got to the store a sales lady approached me and I told her that I wanted a phone which I had seen on the Telkom magazine she then gave me a magazine to show her which phone I wanted which then in the there where two phone the P30 lite for R299 and the P30 prim for R500 but I still chose the one I had told her about before, we then went to her desk and she asked for my documents e.g. ID, payslip and 3 months bank statements, which I gave to her, and I got the phone she told me that the R299 phone came with 900 minutes, 4 gig data for the first 4 month then after 4 months it will be 1gig and that the first debit will be double meaning it will be R600 then after that it will be R299 every month. Month end came for my first debit which was August they took more than R700 well then I thought to myself that is more because maybe there was a fee she forgot to tell me about, September the 4th they debited R987.10 again September the 14th they debited R2073.40 I then went to the store to no help they only told me that I must pay that money because I had asked the bank to reverse it now that it is October Telkom again debited me twice R1709.69 on the 16th October and R1139.78 on the 17th October and worse this month I did get the airtime and the Data they promised since day one I haven't received it and if you go to the store or call their call center you don't get a clear story of what is happening, because really what kind of contract is this from R299 to all those amounts. The last time I called their call center the agent asked me to send her my bank statement which I didn't then she just kept quiet hasn't said anything to me I really need help as I don't know how much will be taken next month in my account and why would they debit me twice every month. I really want this matter solved because I don't understand my they captured my things, is completely different to what I wanted, now my job is to be reversing all of the money they debit, and since I haven't received a call from Telkom of why am I reversing money, instead I'm the one running after them because really this is nonsense. Hi Please if needed I have the paper they gave me after signing the contract and my bank statement to show all the amounts I mentioned above. Hope to hear from you guys soon. Thank youAudrey
