Zero care for distressed clients. Bad customer service!

Someone crashed into my car from Behind on June 30th, my car had to be towed. Monday I spoke to a lady by the name of Claudia who I guess would be the one assisting with processing my claim, I was told that Monday an assessor would be sent to look at the car and that should take 3 days to get a quote, Wednesday I emailed Claudia and to this day she did not bother to respond or give an update, I then called and was told the assessment team had not updated, Thursday I called again and was told the same thing, Friday I called again and was told the same thing, which was very frustrating because we were well pass the 3 days I was initially told about. Today is Monday, 9 June, I called to make yet again another follow-up up only to be told that the assessor went to the wrong location. meaning no one has attended to my matter at all. this is so frustrating and highly disappointing. Such terrible customer service, being in an accident is traumatic enough, dealing with an insurer with such poor service is the worst thing anyone could ever experience. I am highly frustrated and disappointed.
