Trying to get Telkom to Re-install an ADSL Line

We cancelled our landline in the middle of last year along with our ADSL service. Telkom has had my deposit for over a month. As I hadn't heard anything for some weeks I spent several hours every day over the last 3 days trying to contact a comatose lackadaisical call centre to find out what was happening. Apparently, a couple of weeks back, Telkom said they couldn't find our address - no one bothered to pick up a phone and call so that I could be proactive. Anyhow, apparently, despite me providing previous account number, phone number and there version of the address, which is different to the real one - still, I'll play be their rules - they still can't find me. This is even though when their engineers come to fix a fault on other peoples lines, they visit a box located on our wall! This has now been escalated - I'll wait and see if anyone is awake, then phone them (again!) tomorrow. I'm thinking of setting up a poll for the worst call centre service - Telkom, Vodacom, MWEB or FNB!
