Vodacom billing is really bad

This is now becoming extremely problematic , I logged an SR as I was double billed in January 2021. Everything was fine with my billing until I upgraded my fibre line , then all hell broke loose. I was then double billed by Vodacom in January 2021 and subsequently logged at SR*** . Every time I called in to get updates I was informed it was attached to someone and I would get feedback once the issue was resolved . End of February 2021 I never received any feedback and again a debit order was taken from my account but still no update from Vodacom . I then received the below e-mail on Tue, Mar 30 at 9:18 PM SR*** Good Day! I hope this email finds you well. I have passed a credit of R992.31 for the billing dispute of the fibre service, we apologize for any inconvenience caused. I trust the above is in order. This service request will now be closed. Many Thanks and Kind Regards, Peter Ganca Vodacom FTTH Support *** to which I immediately contacted Vodacom to confirm that the billing going forward would be resolved . I then spent another 20min and was convinced by the customer service agent that this issue was resolved . I then checked my account 1st April and I was debited again by Vodacom even after the SR and customer service rep advised it was resolved. When I upgraded my fibre line I budgeted for the upgrade , Vodacom however can’t seem to get a simple line upgrade right and I have been paying double for my current line since January 2021 . I can’t seem to speak to a billing customer care agent but I am allowed to speak to a customer service rep who can’t help but only inform me . I would like to speak to a senior in order to resolve this issue urgently .
