Shameful service

I wrote this email to my insurer, king price, regarding auto magic's ********** service. Good day, Thank you for the professional manner in which you handled and finalised my car accident claim. Your service is first class.Unfortunately, your trusted autobody partner(auto magic) is unprofessional, ************* and play tricks on me. I delivered my car for repairs at their premises on Monday, 28 January,2019 and was told in no uncertain terms that my car would be ready for collection on Tuesday,12 February,2019. I was given regular updates on the progress made to the car for the first week ,but last week I did not receive a single update. These flow of events created an expectation that indeed the car would be ready as promised. Regrettably that promise was never fulfilled. When I called them I was told that I would have to wait two additional weeks because their supplier delivered the wrong parts. How is this possible if they are using the vehicle identification number (vin) to source the parts and are these parts genuine OEM? Currently I have no car and your partner is dismally failing to prioritize my car . This is totally unacceptable and I will never recommend their services to anyone.You have imposed them on me and they are ruining the image of your brand. What a partner!!! You should seriously consider partnering with other reputable and professional panelbeaters. In the unfortunately event that they are your autobody of choice, I will have no other option but to terminate my insurance with you ,once I have my car restored to its original condition. I have lost confidence in them and seek your urgent intervention. Please communicate with them and provide feedback.
