Poor service and poppi act compliant

I am not able to view all my contracts on my mobile app as it keeps saying that the number is already registered by someone else. I have logged this incident more than 3 times and everything someone will come back to me. Vodacom doesn't come back to me at all. I upgraded two weeks ago and now my insurance has been canceled as I was not informed of an admin fee that will be debited immediately and I had to pay for the unpaid debit order charged by my bank. Vodacom service of staff has gone down the drain. I have 4 contracts with them and feel I should take my money to an alternative provided that provides better service.

Hope someone will come back to me this time or maybe I should take this matter up with the ombudsman for not adhering to popping act
