Worst Response Ever

I took my very expensive damaged Jacket to a shop where I was told it is send away for investigation. I was told that the response time would be maximum six to eight weeks. This was done on the 22/08/2017!!! We are now at almost sixteen weeks later. Still no response!! I phoned head office twice now, and was informed I would receive feedback that same day. The one operator even promised feedback within 30 minutes. Guess what - I am still waiting! Worst experience ever!!
