Complain of failure to terminate a service despite numerous follow ups.

I completed a service cancellation form on 1 December 2017. experienced *********** and rude customer care officers. on 18 March 2018 i initiated another cancellation over the same service and to date nothing has happened. i cant access the cancellation department while customer care officers are of no help. there seems to be no escalation process. Telkom stores cannot help me either.
