Shocking customer service - lack of accountability

I have been a loyal Vodacom client for many years and have recently had the worst experience. I ordered a laptop from them in 2021 and returned it as it did not meet my technical requirements. I noticed a random number that I was being billed monthly on, and called them twice to query. I was told that it was additional data and I cannot cancel.

In March 2023, I called and queried this again as I could not find a ****le as per their advice. Turns out that they have been billing me every month for almost 2 years for the laptop that was returned!! I was told that they would cancel this contract, and would credit my account in 7-14 days. I told them I wanted a refund and not a credit and they advised that this would not be a problem.

Needless to say, they have credited my account with less than half of the money due. I call them nearly every 2nd day and keep getting pushed around. They refuse to let me to speak to a manager, and keep telling me they are escalating. I cannot understand how they basically "stole" from me for nearly 2 years and now they cannot be bothered to rectify the account correctly due to their error.

I have had enough of this shocking service as I have had to continue to follow up with them... I am the client! This should have been resolved immediately. I would love for someone to please help to sort this out once and for all. I would like a refund, and not a credit of the balance owed to me.
