Vodacom: ********* Business Practice

For the past 22 months I am experiencing the most ********* and terrible customer service from Vodacom. I took a 2 year 400 gig data contract for R309 from the Vodacom store at the Pavilion Mall in November 2022. The promised upload and download never materialised age all sorts of excuses were given. I complained to the store in early 2021 and was told its a technical issue. I contacted Vodacom H/O and all sorts of trouble shooting exercises was attempted to no avail. I eventual got so frustrated and accepted my fate. Now here's the next problem. My contract was signed for 2 years at R309 pm.. The very next month it increased.. When i brought this to Vodacom attention, an adjustment was made to my account.. Few months later my debit order amount increased.. I contacted the customer care and was sent from pillar post. This year, the debit order amount increased 2 x.. When worried this, I was told its their annual increase.. So here's my question, what does ANNUAL increase mean? Can contracts be amended during term of the contract.. Vodacom seems to think their internal policies supersedes the country's laws.. I asked for a copy my contract last month and am still awaiting same. I suspect my contract does not allow for these willy nilly increases.. That's why they will not provide copy of this contract.. I unfortunately misplaced my contract.. Vodacom, you are a horrible company.. Your previous and current GCEO are the reasons why management and staff treat customers so poorly and *********ly.. I may have been prejudiced with this contract.. But karma will ensure you pay in the billions to the Please Call Me Inventor. Further you are going to fail when Starlink officially comes into SA..
