Extremely disappointed with service, Regretful choice

I have a warranty plan with Auto and General. I logged a claim 3 weeks ago to have the gearbox serviced. My vehicle is with the service provider for 3 weeks +. I have the same response everyday that they are waiting for the assessor to approve the claim. My car was driveable, not in an accident, just a gearbox service. I am at my wits- end as there is no communication or progress whatsoever. Anele is handling my claim, no communication, not expediting or escalating this matter, can't even reach him, ***********.Can someone please help at A&G🙏🙏🙏 I need my car back ASAP..My premiums are up to date, so is my car payment but I don't have a car to drive. Not impressed.
