Call ID problem not able to be fixed

Have logged numerous faults with Telkom over the past month to rectify a problem with my Caller ID service. I keep getting asked to rate their service via SMS but the problem has never been fixed. One person (will remain nameless for now) even gave me someone else's name when he logged the call reference. Next step is for me to cancel the Caller ID service as I'm paying for something Telkom us unable to provide.
