Vodacom Fibre poor service

Vodacom Fibre is absolutely useless. I phoned to cancel my contract on the 19.01.2023, the lady doing the cancellations convinced me to take a better deal at a better price - which is a 50mbps line for R699 and I will receive a new router. I immediately signed my contact. I followed up on the new router on the 31.01.2023, because I haven't received any news back from Vodacom. On 01.02.2023 they deduct the R743.08 which was for my current 20mbps line still. I immediately followed up spoke to the 4th person. They informed me that I do not need a new router and that they can only generate invoices at the end of the month - so I have to wait a month for anything to be corrected. Came the 01.03.2023 they deducted the R743.08 again and I am still on a 20mbps line - I followed up again and spoke to the 5th consultant saying he will log a call with the billing department because the billing department cannot receive calls directly. And on the 03.03.2023 I receive an invoice where Vodacom is charging me R2175.01 for two months of a 100mbps line.

Which means they are billing me twice for two different lines but worst part of it all I never signed for a 100mbps line. And I refuse to pay that amount of money for their mistake, and I am not going to wait a month for a credit!

I expect a call back from Vodacom immediately with a solution and the invoices/statements fixed!
