Poor service and ******** when it comes to their customers complains.

I have a problem with my billing from Vumatel on the 02/02/2026 i pay 429 for the service and again they company to the amount of R253 on the 16/02/2026. I did contact the customer service and they refuse to refund my money. I dont know why i have to pay twice in one month. I dont trust this people im trying to cancel the internet with them. The is no contract only month to month contract but why the debit my money on the 16/02/2026.
