Customer suffers - the fight between car insurance and panel beater

2 weeks ago I posted about a terrible service I received from standard bank car insurance , that my car was bumped on the 26 January 2018 and was towed to nearby panel beater, until today is till standing still there nothing has been done. Consultant by the name of Freddy keeps on saying the matter has been escalated and will give me a feed back soon and every time I'm the one calling him. I talked to Cathleen Samuels (manager) last week, she also promised that they are attending to the matter and will keep me posted and never did and will communicate with panel beater to hear how many days will they take to fix the car after it has been transferred to them and she will extend the courtesy car days according to that . Today I received a phone call from the car rental company asking me what time will I bring the car today. That Cathleen didn't extend the days as she promised. I called in for senior management intervention all of them are not picking up their phones i.e Kirk van Wyk, Ragin Govendor , Cathleen Samuels and the complaint consultant Wilhelmina . I don't know what to do now. WHAT A TERRIBLE SERVICE I RECEIVED from STANDARD BANK CAR INSURANCE.
