Poor Service

I took my car in for repairs referred by my insurance company on the 19th of August 2015, i was told that it is only going to take 10 working days by the manager after the 10 working days i was expecting to get my car back but no i did not. On the 10th day they started sending me sms saying \dear client as discussed the expected completion of your vehicle has changed to 2015/09/09"on the 9th i phoned and asked them what time should i come in to collect my car they now told me that they are waiting for the suppliers they send me another sms say my car was going to be completed on the 18th/9/2015 on the 18th same thing happened i was ready to go collect my car i phoned and find out at what time should i come they guy that i spoke to told me they are just painting it it will be ready for collection on the 22nd no1 called me this morning i got the sms saying it will be ready on the 30/9/2015<br> This they told me they are still waiting for the suppliers its been a month and a half from 19th till to date i am very unhappy about the service and i am sitting without transport they should have told me the truth from the word go rather raising my hopes up.
