Gearbox and clutch back n forth claim

I sent in my car at the dealer listed Monday for my car to be sorted the gearbox and clutch, no communication throughout the week and to my expectation as promised that Friday my car will be sorted, I called in the deal only to find that nothing has been done as the dealer is waiting on M-Sure. So I than called M-Sure for a follow up only to be told that I have to be a middle man wasting my airtime trying to find out what is happening with my car. Approval has been pending as per the dealer from Wednesday. My calling started from 10am morning for the to be called by me again at 1h45 only then we have a way forward in getting a conference call between us 3 parties. Seems like I will have no car for another week and have to Uber which is unnecessary costs. When I called and Spoke to Yonela she explained that only Nhlanhla as the team leader can do authorization which I find very crazy. I have been hearing that M-Sure isn't the best only now I find this when I have a claim pending.
