Appalling service at Telkom Contact Centre

Telkom had incorrectly billed me for 2 months. The query was assigned to Given in the billing department who then went on leave. My query was not attended to until she was back. It is now 2 weeks later and I am told that I will have to wait 72 hours for her to check if the wavering of the charges were approved by the System Administrator then the credit will be done and then my refund. The service is appalling. Contact centre agents dropped the call on me. No managers return the call after numerous requests at the call centre. No feedback. Just a bad attitude from everyone.
