Call Centre Unable to provide a basic service

I recently relocated from Pretoria to Cape Town, and wanted to relocate my ADSL service as such. I have now phoned the call centre to try and have the new line installed or even just ordered on a couple of occasions. The problem starts when I give them my new address, and for some reason they can't find it on their system. A simple Google maps search returns the address as clear as daylight, the property has been there for at least 15 years, and there is a Telkom line installed, I just cannot get anyone to provide me with the number. So when the call centre fails to get the address they either hang up, or place me on hold indefinitely. So frustrating when they can't be bothered to help. Absolute ******* customer service! Only rated a 1 because a 0 is not available...
