Vodacom again going out of their way to make life hard

Okay I don't even know where to start with this company anymore. I went to the Vodacom shop in Brits mall to add a new number to my already multiple-year existing contract with Vodacom and cancel and expiring one. So after hours and hours of struggling to get this done, they now created a brand new account for the new number and left the fiber and the additional cellphone contracts I have on my initial account. Now I get a debit order going off at one amount, receive one invoice for my new number, My other contracts are now now on a different vodacom account and the customer care said I must go back to the "wait in a row for 3 hours" vodacom shop AGAIN and ask them to do what I asked them to do in the first place. They have also not updated any of my addresses and by statements and invoices are exactly as I told them it should not be. Wrong email, wrong address (even after submitting proof of residence), now I have tow accounts, one incorrect or incomplete invoice with different amounts towards what they take from my back account and this is now my problem to fix. I have to go back to that vodashop and plead with them to do what I asked AGAIN
