Disgruntled ex Vodacom customer.

I did an upgrade in December 2022, the handset and accessories were never delivered. It took Vodacom 11 months to confirm that ***** had taken place.( about 50hrs of calls, many visits to the Vodacom shop at the Newmarket Mall) Since then I was promised a credit of approximately R1000 per month, the difference between the old and the new contract, I was also promised that the account would be cancelled as of the end of January 2024. Vocom has not cancelled the contract and is harassing me to pay them R2400. I have now refused to pay. No one at Vodacom has done anything to resolve my issue, I was a loyal customer for over 20 years.
