BAD service all around

I have upgraded in November 2017, since the beginning of this upgrade I had problems. And this is not the first time. It looks like every upgrade is a headache waiting to happen now. Firstly I couldn't upgrade on the website, so I phoned. The person doing the upgrade obviously doesn't know what they are doing because it took almost a month for the phone to come, after a fee calls they discovered the problem. After that they deducted admin fees that they shouldn't have, I reported it and the guy said it would be credited into my account. Obviously again that didn't happen so yet another call to you Vodacom they decided they will credit it from the next months account, which I did not ask for. You take a persons petrol money and then is reluctant to pay it back. So today I decided to just check if its been done, so yet another surprise awaited me when I checked the account online. This time insurance was loaded which I did not ask for. I am really sick and tired of struggling every month with different nonsense. I asked them to take off the insurance but now they want proof that I did not ask for it, which is total nonsense. Now I am trying to get the recording which will show the proof that I did not ask for it but they keep on putting me through with no help.
