Discovery never calls you back !!!

Discovery never calls you back when you log any issues with them. Couple of months ago, I have asked discovery to update my SA ID and driving license. They have increased my premium after updating my details stating that my license is just a month old, but the fact is that I was driving with foreign license since 2001. I have called many times to discovery but they never called me back for the feedback or update. I have almost wasted around 150 rands to call them. when I asked them why are they not calling back for the feedback, they just rep**** with apologies. That's the first part. Now the second part is, Discovery has messed up my profile in Discovery Insure. My Discovery Insure app was no longer to reflect driving records to my profile. When I called them, they said it's the issue with Tiger Wheel & Tyre. I drove to Tiger Wheel & Tyre, they investigated and found that Discovery has messed up my profile while updating my ID and driving license. I have again called Discovery, they agreed with the issue and promised me the resolution within 24 hours with all my lost rewards, iphone cash back, weekly play, etc. It had been 5 days, but no call or resolution from Discovery, so I called them for the feedback. They said it's still in the process. Now, today is 14th Sept, still no call or resolution from Discovery. Again, discovery never called back. I have again wasted around 100 rands just to call discovery for the feedback. I don't know why discovery never calls back and just rep**** with apologies. I don't want apologies from discovery, I want better service from them. If Discovery don't accept my apologies instead of monthly premium, then why do I? There is no minus rating, else I would set minus rating for them.
