Bad customer service

1. I took out a contract with Vodacom last year around June/July 2. The consultant input the incorrect debit date and the first 2 debits bounced. I also did not recieve my Sim card and I have not enjoyed the benefits since. 3. I made contact with Vodacom head office to sort out the issue and make arrangements to pay the 2 months that I owe and also make arramgents for me to recieve my Simcard, which they agreed they will do. 3. A month later after I contacted the head office they debited the entire amount which was not on the agreement. They still have not delivered my simcard 4. I reversed the funds and made contact with them again to make arrangements for me to pay over the debt over 2 months and still pay for my contract, they agreed again. 5. A month passes and I don't recieve my statement and I get a notice that I have been handed over to their lawyers. 6. A lady contacts me from the lawyers I was handed too, I explain my story and even send her an email regarding my issues which she says she will assist with. But no assistance came from that. 7. I recieve an sms saying I'm owing R10k and I can get a discount during this COVID-19 crisis.

Now vodacom has given me a bad credit with something that was going to be avoided had the consultant said they will do what they said they would. How do I now resolve this issue as I belive it would have been avoided had everything been resolved when it should have been. I don't even have a simcard nor do I know my vodacom number. I have been trying to get someone to get in touch with me to resolve my query to no avail. I'm very angry and disappointed at the service I got from vodacom which resulted in my credit record being tarnished.
