The worst service I ever received...

I was involved in a collision on the 9th of December 2017. I was assured by my insurance that Renew-it Randburg are the "go-to-guys". By middle December my insurance phoned me and told me that the go ahead was given to start repairs on my vehicle...It is almost 3 months later and I am still without my vehicle. I e-mailed Renew-it last week Monday because I noticed there was a hold up on my vehicles repair via the " track your progress" option on their website. When I enquired they came back to me only on Friday and told me they had to order mounts and brackets that didn't come with the bumper, and that these parts have arrived and that they are resuming assembly on Monday, and that my vehicle might be completed on Friday. Yesterday they phoned me again and told me that they are still trying to find a bumper for my car....I regard this as highly unprofessional. They knew that they were going to have to order a new bumper the day I was given the quote in middle December, why do they only order it now? I don't know what is going on? What is the truth, who is lying to me and who is telling the truth. Fact is I am stranded without a vehicle for almost 3 months now and have no means to go to Randburg and go and inspect what is going on. UNPROFESSIONAL!
