Appalling Client Service

I am highly, highly irritated with the service of Telkom. For some unknown reason (like several other people I have encountered on here and other websites), I have been charged a fee of R600+ by Trudon for a directory service I apparently subscribed to. When phoning Telkom, I was told that I need to phone Trudon myself - never in my life have I spoken to them, and never in my life have I agreed to any sort of service with them.

I am paying Telkom. I am not paying Trudon. Telkom need to fix my problem. Telkom said they are in partnership with Trudon - have you seen how many complaints have been laid against Trudon over the past year or so? And yet Telkom dont want to do anything about it?

I am highly irritated. I suggest someone resolve this for me urgently. I NEVER agreed to any subscription of this nature - so why on earth am I being charged this fee?

Thanks.
