NDS ARE FULL OF ****S

NDS is providing terrible service and they are **** people. My Cell C account was handed over to them due to an issue by Cell C. However I paid the account in May 2022 after being contacted every day by NDS like I was a ******** when the error was not on my side. After making the payment I was contacted once again by them and was told to send proof of payment and they would transfer it to Cell C and send me a paid up letter. To date they haven't done so and trying to contacting them is a nightmare.
