TELKOM:UNFAIRNESS

I am Fikile i took contracts with Telkom 2years ago 2017 . Telkom sent me a reminder that contract was coming to an end I went to Lenasia to renew contract and I was told to bring proof of adress , certified ID of which I didn’t bring that moment and I told the guy who was helping me I will cancel the contract for now , February Telkom did a debit order (R149)which I assume was the last debit order , March I reversed it , April did a double Debbie order for February and I didn’t reversed it than on the 20 of May 2019 I called them to cancel the contract asked them if I should put it on writing they told me no there’s no need account will be closed since it’s up to date of which they debitted month end of May (168.46) of which is more with (R19.46 which I reversed) , June debit order went off I reversed it ( R353.73) In July the 15th they debited for an amount of (R556.43) which bounced , 16 July I went to a shop Carnival Mall and spoke to a very rude guy ( Eugene De Jong ) who raised his voice until I told him that what we discussing is between me and him not the whole shop , My problem with this whole ordeal is no one told me that if I close this acc in May I need to pay more even if the account is closed , No one told me that they will be going into my account to debit money on those akwards days of the month , I am very unhappy with the treatment I’m receiving with Telkom after such a long relationship we had , please help me sort this issue out please as it countinue to tarnish my credit reputation.
