Telkom making FALSE promises to their clients

In February Telkom phone me and apologised to me for the bad service, and offered me there new wireless service. Telkom told me that the wireless phone and router will be given to me for free! I waited one month for the devises to be delivered, and another month for the service too be activated. Today Telkom have sent me Aprils invoice. They have charged me for the FREE phone and router. I had originally taken an ADSL service from Telkom. And then suddenly the service just stopped, it then went on and off for a bit. Then it stopped! Telkom told me it was due to cable theft but for two years Telkom has been deducting from my account; the full amount for a service that does not exist!
