Paid twice for the landline but have not received it for 8 months now

I have paid twice for Telkom to give activate my landline number and each time I follow up I am told that the money was allocated to some usage I am not even linked on.

Telkom cannot then claim to care about the community if they do not provide services. I have had it with them since last year November my lines do not work. When I paid initially, I was told to send proof and my banking statement which I did, until I decided to pay another R1000 which was also allocated to some service I am not subscribed to...
