Firestream problem.

I chose Firestream in October last year for a new service provider, but they never delivered their modem. Upon trying to get another service provider I was told that they cannot help me, as Firestream blocked the line. Mark from Firestream said if I signed up again, they will deliver and start their servive. Filled in the new forms in February and .... . Nothing happened yet again!!! I now want to use a different service provider (one that actually wants my business) but Firestream blocked the line. They say it is Vumatel's mistake, but between Firestream and Vumatel I still cant use the fibre after the installation in October last year.
