SHOCKING SERVICE FROM MWEB

I cancelled my service with MWeb to end January 2020, paid for a full month's service, however MWeb decided to cancel my service on the 20 January 2020. I phoned their technical department immediately and they informed me that they would ensure that the service is back on line the same day. After 3 phone calls to the Technical Department with several promises NOTHING happened. At the end of January I phoned the Billing Department regarding a credit for the non usage days. Consultant promised to sort out and phone back. DID NOT HAPPEN. I phoned again on Monday 3 Feb and consultant put the phone down on me. Obviously NO ONE is interested in servicing clients, especially after the service has been cancelled. I have emailed MWeb twice on their on line portal and also NO RESPONSE! The service is shocking to say the least! I have had to also phone from a cell phone and listen to all their garbage whilst paying for a call and holding on forever. Why should they care, they are not paying for the calls and also refuse to phone clients back? I am insisting on a credit for the 11 days that my service was deactivated.
