Terrible service

Discovery claims to be "passionate about delivering exceptional service" - that is clearly just lip service and all for show. They ask for our feedback which I provided and even that gets ignored. I was on a call for 45 minutes with Discovery with most of that time being put on hold trying to resolve and issue that should have been pretty straightforward. I had to leave the call and the lady assisting assured me she would phone back in an hour - it is now two weeks later and I am still waiting for the call. Then I get another call from the Debt administration team saying that something had been calculated incorrectly with Dischem and demanding that it needs to be repaid. I tried to get more information but big surprise, you can't actually email anybody to get assistance - so I emailed all the addresses I had. I received a mail today with the supposed details which said "we have received and processed the claim reference number ***xx". Does Discovery like being deliberately obtuse? Apparently so as no actual details are given and you can't even respond to the mail. I am so sick of the poor service Discovery continually dishes out (this has just been another incident in a list of incidents dealing with poor service from them). We pay a fortune just to have to deal with the 'big bully in the playground'
