Call Centre- Ineffectiveness

I have two Telkom mobile contracts- I called into the call center 3 weeks ago to activate a value added service - enabling me to call specific landlines at a discount rate for free. Initial call- the request was incomplete and needed to be sent to supervisor. A follow up call I made- to ''LEthu''- 2 weeks later- was meant to be followed up and myself contacted again but this was unreturned. Finally called in today 22-10-15- but once again could not resolve issue as system was offline. It's shocking that consultants aren't to view and check on the status of services pending, unable to provide you with reference numbers for calls, and also don't have a designated complaints email system ( according to consultant). I would like feedback and cancellation of my additional value added services as the delay and waste of time has forced me to make alternative arrangements. Looking forward to a reply from someone- and to end my equiries once and for all. <br> Thanks
