Incompatency in the business of Vodacom

I have been a customer with Vodacom for over 25years now and was happy until 2019 when I found that my employment was under the threat of slowing down and eventually coming to an end. So I sent email, after email asking for my contract to be canceled due to the fact that my employment was coming to an end. These emails were often ignored and so I became increasingly frustrated when I was still receiving invoices pertaining to the contract. After some time of continued emails, I was eventually handed over and began receiving demands from various debt collectors. after several debt collection companies received my proof of emails and so on, I eventually received a call from Vodacom and I was able to reach an agreement that eventually became a resolution whereby the contract was canceled and payment was no longer needed. Or so I thought, until 29th January I received a demand for payment to the tune of 131 rands to my account number NA034280. This was puzzling me, so I delved into the reasons and investigated, I have now discovered that, to my chagrin, there is an account attached to my name and ID number that is of a phone number of which I am completely unaware. This is a number that belongs to another person of a different name. I am now in full belief that Vodacom, as a company, is completely inadequate in its ability to run successfully! I have therefore come to the conclusion that Vodacom has deteriorated exponentially as far as customer care is concerned. and that I recommend that all and sundry of the client base should be very wary of how things are run in the business.
