********** Debit orders

I took out a contract with Telkom at their store in Mall@carnival in February. I was helped by Shadley. The contract I took is R179.00 for a Huawei P8. Shadley advised me that my contract amount will be R179 per month but on the 25th March they will debit a pro rata amount of R360.00. I was very specific to Shadley that I dont want to pay anything over the stipulated amount due to affordability reasons. To my shock when the first on the 2nd of April I was billed an amount of R873. Firstly I never even received any statement to inform me of this. I went to the store to complain and Shadley logged a query of which I advised that I will reverse the funds from my bank and do an EFT which I did the very next day. He also advised that moving foward my issue has been solved and my monthly repayment is R179 nothing more. To my shoch this morning a debit order of R703.93 has been taken off my account. I want Shadley and Telkom to show me where I signed and gave them authority to debit my account as and when they please and who signed for these amounts. I dont know what product was sold to me that shot up from R179 to over R1000 a month. My account is being de*****ed by Telkom and their rep sold me a phone **********ly. I want Telkom to cancel this contract. According to the NCR a service provider is not allowed to over indebt a client which is what Telkom is currently doing. I am going to drop off this phone at their store they can see to finish what to do with it but I am contacting the NCR regarding this issue cause I cannot afford these amounts going off my account **********ly. People warned me against doing any bussiness as they are ripoffs now I am learning the hard way. Fellow South Africans stay away from Telkom Mobile they are **********.
