No feedback

I reported a claim on Monday, 17/08/2015 to iWYZE and a claim was registered (sms notification was received with the claim number). My vehicle was assessed on Tuesday, 18/08/015 and on Wednesday, 19/08/2015 I received another sms from iWYZE that reads: We are still in the process of validating your claim. Then it was quiet until Monday, 24/8 when I contacted iWYZE to follow up on my claim. I was told that my claim was authorised on 19/8/2015. I asked why I was not informed and I checked whether a courtesy car had been arranged for me and as I expected it was not. The gentleman who took my call contacted someone else who said I must take my car in today. I told him that I will only be able to take it in once it is confirmed that the courtesy car has been booked and ready for collection. He mentioned that he booked it but since it was after 3pm no confirmation could be received at that stage from Avis.I am still waiting for a telephone call to give me feedback about my claim and confirm the availability of a courtesy car.Do I always have to post a complaint here in order to be taken seriously by iWYZE? Or maybe I have overstayed my welcome at iWYZE. I'm not impressed at all.
