Extremely unsatisfied fibre client

I signed up for a promotional fiber package in November 2022. Fiber was activated on the 30th Of November 2022. My first invoice was received on the 13th of January 2023 which stated the full amounts to be paid for December 22 and January 23 at R699. It was supposed to be R199 p/m for the first three months. I logged a call on the 14th of January 23 with Vodacom and after multiple phone calls and email requests, this issue has not been resolved yet. Received my new invoice today and still the issue has not been resolved. Vodacom is very quick to take your money, but paying ack, not so much.
