Receiving bills but no service

I asked for my landline to be relocated 2 streets away from my previous home. After 2 months they tell me that there are no copper lines in the new building and that I will need a wireless device- which the area manager then app**** for. I've been billed for August which I paid and now September too but still haven't received anything. Now I'm told to go to menlyn and fetch the device myself but when I try to call the store there- no answer. I cannot go all the way there only for them to tell me they can't issue me with the device. It's 2 months and I've been transferred from pillar to post with no help whatsoever from anyone. Please help.
