Telkom contract nightmare

I regret the day I joined telkom contracts. I took a contract for the lit bundle since I was buying lit bundles on prepaid, I then realised that I wont be able to pay it if at work they don't renew my contract, so I cancelled the contract within 30 days my bill was going to be 620 in september so I changed the date of the debit to be on the 30th of september the consulted told me I will only be debited the last day of October since I changed my debit date which means it would be 932 fine was cool with that but then on the 5th of October they debited then I was confused, the amount I had on my account was less than 620 since I didn't budget for that because I was told I will pay last day of October so the debit order bounced. I called then they said no its fine they will include it on the last payment fine no problem. During that time I get a call from the cancellation department which the consultant advised that I can take the smartboard deal without a divice but whats nice its that it will be more like prepaid so any time I want to back down I can with no hustle and advised me that he has cancelled the initial contract I had ( there i had no problem still). Problems started when Telkom debited the 932 I owed for the 3 month on the last day of October then debited the 620 which I reversed because according to my knowledge that 620 was included on the 932 which they debited, on the 5th again they debited I called and told the call center that they had already taken the money I owe I don't understand why do they still debit the 620. Then I get my statement the amount I have to pay is 512 but my deal was supposed to be 300 then I was told yesterday that the 200 is because my account was handed over to the lawyers without my knowledge to SMS no email that my account is being handed over. According to what I know is that if you account is like that they disable your sim card my sim card was working fine but they handed over my account. When I was to cancel the deal the consultant tells me that there is a fee I will pay because on his side the contract stipulates that it will end in 2021 so I told him that the first person I talked to advised that he has cancelled that contract so I don't understand what is he talking about. The only money I am willing to pay is the 512 that's it nothing more. This is the first time ever this happens I had a contract with MTN and everything was fine until the end, telkom has nice deals but be very careful when you take the contract.
