MWEB Terrible Customer service - Billing Query Overcharged.

I am truly disappointed with MWEB, the company has overcharged my billing for this month (Double charged my Openserve line and the evotel line which was supposed to canceled which they did not.) and when i try to get in contact with them the customer service center is terrible. I was waiting for a consultant for 17min until i decide i had to hang up the call. Complained on Twitter i was simply told to download their app and raise a query, that was around 14h00 on the 1st of November 2023, guess what i had already done that at 08h15 and when i responded that i had done it already they went AWOL as usual. I want my money back simple as that, we have only agreed on R559 not R1700, i need that money back. I'm literally hoping that you fix the customer service and ensure that you guys service us as paying clients, I need a resolution to this issue.
