Bad Service

I’m on Telkom contract and I pay via debit order but in December I made a payment earlier via direct deposit because I got paid earlier. In January I receive an sms stating that my account is in arrears and I called to query about it , the agent I spoke to told me I shouldn’t be worried because on their side it shows that I don’t owe anything , it’s R0.00 . Today on the 24th my simcard got locked, no access to the internet and when I called Telkom they said it’s because my account is in arrears and I am ****ed because the last agent I spoke to assured me that nothing is going to happens. And that inconvenienced me , I was told that I should wait 24hours for my network to be reinstated. Now I have to switch SIM cards but they couldn’t do their job. It’s not the first time this has happened, in 2018 it happened hence I repeatedly asked the agent I spoke to in January 2019 that my simcard is not going to be denied access to the internet and calls .
