Lying to you to retain you and your debit order

I cancelled all my contracts with Vodacom because of poor service. Then they called me to retain me with discounted offers. I went ahead with 3 upgrades but did not extend the fibre because it is so poor in my area. The one upgrade was never done and I went ahead with another service provider bit for 2 I received confirmation. Today on the 1st of the month my data for one was not added and wrong for the other. I called the call center this morning, they did not have a clue, kept asking me to hold, then said I was not given the data. I refferred them to my invoice that clearly show the monthly contract, more holding and then eventually she told me it will be fixed in an hour. That was this morning and it is still not fixed. Honestly, how can you give clients contracts to retain them and then you cannot even honor the contracts. Probably just lies to get more money from you. They are already in contravention with the CPA because of their cancellation notice period and now they also lie to keep your debit order going
