The most Useless excuse of a Internet service provider

The worst customer service I have ever experienced from Gerswin & Razia. Have been without Wifi for a week and still counting due to RSA web not being to lift the previous contract which is cancelled at this address. Notice was given on the 29th of July that we were moving and their response when you call is to say "We have emailed our account manager at vumatel and will have to wait 48 hours"... Its been 2 weeks of them saying thus but still want to charge me for the old address whilst there is no wifi at either the old or new address.
