bad service

I had an accident and submitted a claim with mi way insurance company and they claim handler was very helpful and assisted me as my car was at vw at first then was request to tow my car to this centurion guys as vw is not on mi way panel and vw promised that my car can be fixed in 2 days but then I was patient with this centurion panel beaters without any feedbck from them I then today 11/05/2015 decided to call them and follow up because they were Authorised on the 5/05/2015 after mi way advised me...what a bad service I received... I called using my airtime and was told they ordered the parts to repair my vehicle and when I ask when they will be receiving those parts they told me they don't know..did they ever followed up with the order? Did they call me to update? It's been more than 48 hrs since claim approved and no courtesy call ..worse part of it you don't know when is my car going to be repaired meaning it can take a year even, mi way must just interven cause this company don't deserve to be in their panel...now I want my car back or mi way take my car to vw for repairs since they willing to help me. this is how we loose clients
