Cancellation of service

This is now my second complaint in month of the bad service of Telkom Mobile. On the 16th of March 2016 I complained on Hello Peter regarding the bad service from Telkom Mobile and a Wesley communicated back that someone from the cancellations department will contact me. Today, the 30th of March 2016, no one contacted me as yet. On the 14th of Feb 2016 I sent a request through to cancel my contract/service, Telkom's respond was within in 20 days. Well my next debt order will be running on the 1st of April and once I'm going to pay for something that I'm not using. Now the refund from Telkom Mobile's side is climbing to 20 month. Hopefully someone will contact me via telephone and through sms of email!!!!!
