*****ing data from customers

I cancelled my contract with Afrihost after their customer service drove me to distraction. There was still data on my account and the contract had some time to run with some carry over. Nevertheless all my routers were unplugged as we had moved onto Fibre. Next thing I get emails doing automatic top ups with my credit card. When I queried this and explained we are not using any data - they referred the usage coming from a Cape Town number that as absolutely nothing to do with us as we are based in Johannesburg. On calling their accounts department this morning afrihost tell us they are "Looking into it" and they don't know how long it will take. Quick take peoples money which I regard as theft, but no commitment to refunding it when they are caught out. I wonder how many other people this has happened to who haven't picked it up???
