Shocking Service

I had an accident in August and my insurance told me to take my car to Automagic. My car was assesed and booked in on the 4th of September. At fist they told me my car would be ready on the 17th. On the 14th i was told there was a delay of one day as there was a lack of electricity which is reasonable. I hear nothing until on the 14th I called to confirm if my car was ready which it was not. Days of not hearing an update I was told on the 21st that my car would be ready on the 28th. I called Automagic on the 27th again to arrange collection and again I was told it would be delayed again and only be ready on the 2nd of October. I again called on the 1st to inquire if my car was ready and again I was told its still in the paint preparation bay. I have to return my rental car on Sunday as i only have it for 30 days. I am now stuck without transport. This is a complete disgrace and the service is absolutely shocking!! I can't believe i have to call to find out whats going on and I'm not kept posted!! The least they could have done is offer a courtesy car!! But obvously they couldn't care less they are getting paid by my insurance either way. The lack of customer service is shocking!!!
