MWEB - Service Provider, I don't think so!!!

My email address was hacked and I have been trying to contact MWEB for days. I went to their offices in N1 City only to find that they have moved and the guard at the gate told me they had moved to Century City in the MTN building. Guess what - when I went there they said that people kept coming there all the time but that they were not in that building and when I checked with the offices of Century City they told me that MWEB did not have offices there. I cannot sit for hours waiting for a technician on the chat line and when you phone MWEB you use up all your data whilst they play an annoying tune but never respond. Someone managed to intercept an incoming email with a bill attached for R22000 and changed the banking details and then sent it to me so that I paid it before realising that they had changed the bank. You would think that in circumstances like this you would be able to get hold of someone at MWEB - WRONG they take your money for your Wifi and email address but help is just not forthcoming. I am so furious at having been conned like this as you would think that your email address is a safe domain and that help would be forthcoming from MWEB but if you can't contact them what do you do?
