MWEB Customer Services (Non Sevices)

I have been to trying to arrange a simple move from one property to another but without success. I have spent 109 minutes in the phone to MWEB Move without resolution. The simple error I have had to establish is that they have a billing error In that the address I have moved to is registered incorrectly to someone else. Therefore they say there is a live account to my address. But the live account is in the building next door. I cannot get anyone to fix this simple problem as every time you speak to someone new and have to start all over again. No one takes responsibility and one cannot speak to someone with authority or the ability to fix the problem. I have spent a substantial amount of money on data trying to keep my business running not to mention the cost of the calls. I am at the stage where I have no option but to try and get hold of Ettiene Cloete GM of Mweb Customer Support as the MWEB staff are not taking me seriously.
