Migrating from ADSL to Wireless - A NO JOY EVENT !!!

I was requested by Telkom to migrate from ADSL to wireless, was assured that the sytem would be more stable and that all three my telephone extensions at home would work. I have had no joy since the migration took place with very limeted uptime and only one telephone extension working. I have reported the faulty line on several ocasions and was assured that it works but still no joy. Even now when I phone my home number it doesn't ring but somehow goes to an automatic answering service. Last week, I had an encouraging call from Keegan at Telkom to assure me that Telkom will urgently look into the matter and resolve the problem. When I asked about the three telephone extensions, he told me that this was not possible and that Telkom staff misinformed me. I asked that I rather migrate back to ADSL as this was working just fine but have not had any answer to this either. Just a few months ago I renewed the service contract for anither 24 months. Telkom, if you cannot give me the service, rather release me from the contract - I am sure I will find another service provider !!!
