Bad customer service

I made a claim on the 15 March 2022 and it was approved. I was told that the car parts which are a battery, spare wheel and lock system and jek will be delivered to the panelbeater on the 29th until today it not delivered. I have called them and they telling me that the driver is out to deliver the parts. It's two day now waiting for that parts like really. It been three weeks that they fixing my car. Am very disappointed in the service they providing and they sending me an sms telling me that the premium is increasing with a R200.
