Bad customer service

I had a contract with Telkom after a year I went to the shop ask what and how much to pay to close the contract. the guy by Telkom greenstone mall gave me a settlement amount I went to game store to pay, and went back to the store with the proof of payment then the closed my contract and convert my number to prepaid, after few months I’ve received a call from Telkom saying I’m owing them, I’ve ask them to explain the money to me they failed to give me an answer,secondly I received a call from other one from call centre she asked me to send a proof of pay I did and promised to come back to me even now I’m waiting, I also received a call from the company Telkom is using to collect their money I’ve asked the guy the reason why I’m handed over to them no answer🤔today 25 April 2023 I’ve received an email from that company for veri cret collection giving me bank account to pay,I went again to Telkom greenstone for them to check their system and give me answers ,they connected me with customer service over my phone then I’ve verified my details then the lady said I must hold, I’ve asked her if it cuts off please phone me back she said no we don’t call out I must recall and restart with another person she didn’t even bother to check for me what’s happening she put my call on the customer Service rate, that’s what happened, I’m not happy about Telkom can someone from Telkom call me with full info on my account and reasons for taking me to collectors,and also the recordings of all my calls as they say the keep them. I won’t recommend Telkom to anyone they are ****ming us I’m expecting their call within 24 hours ***
