Worst customer service I have ever experienced, with absolute no feedback

The worst customer service I have ever experienced.

After having a payment agreement with Vodacom to settle my account, while my sim was reverted to prepaid, my sim got soft locked. I phoned Vodacom to find out more on the case, where they appologized and said they have received payment earlier that month and my services will be reinstated that same day. Later that day I found out that my number has been deleted from the system. So for business purposes this is also very bad if a client calls me only to hear "the number you have dialed does not exist".

I have been trying to resolve this issue with Vodacom for almost 4 weeks now, phoning in about every 3 days and also going in to the store, where each time they would admit that it was a technical fault on their side, and that the case will be sent up to higher management.

I did stick with my payment arrangement, where as Vodacom from their side could not care less, and all that I am told is "sorry" and the account can be settled, where as I can get a new number, but my number can not be recoverd.
