Still it continues!

I suppose I should have heeded all the warnings from Vodacom that I should not remain with them, but guess what I did more to my sorrow. So, they finally sent me a new phone and were very apologetic about what went before, and they said they were working on the problem with regards to their service. I believed them! I now have a new phone which required me to use the sim they sent with the phone as it is one of those 'nano' sims and I was advised not to cut my old sim. So yesterday I started trying to activate my card, phoned them, and they said they were too busy (I wonder why) call back later. So I went onto myvodacom site, and I could see that I could do it there, great four attempts and 3 OTP later it would not work (guess that has not been improved yet). So I called the customer care line again and finally got through. The consultant then went through all the information confirming who I am, and it appeared he could not find me, so I told him I am on the old system and he said he looked there, and that I was not there and I was to hold on, guess what he cut me off! So today I went onto myvodacom again and tried to update my sim, same problem! Tried to find out how to update the firmware on my ****le (which I also upgraded) and it said it could not connect with Vodacom. I phoned customer care again and got a lady who told me that she could not help me as it was not their department. She said I was to phone 100 or 081945 (I confirmed the number listen to the recording), I also confirmed which phone I should call from new or old, and I was told the new one. So I asked her why I had not been told this yesterday and why had I been cut off, all she could say was it was not their department. I tried both numbers on the new phone twice and guessed it they said: "Not registered on network". I thought let me try on the old phone, and both numbers said they don't exist! I don't have more time to waste on this!
