Poor service delivery

I recently had my car ****** and recovered a week later. Now 7 weeks down the line I am now being investigated by a forensic investigator for reasons that have still not been reasonably explained. Initial investigation was kosher and then when Assessor asks for engine to be stripped to find out why it doesn't start I am then told that it's now handed to external investigators. After being questioned like a ******** I am told that beacon and billings information is required. I willingly oblige as I have nothing to hide.Investigation still continues but Hollard says they prepared to settle me an amount to pay the panel beaters and which absolves them from any further dealings with repairs of my car. My point is that if further repairs are required I will be accountable to fit the bill whereas I have dutifully paid my premiums. Yesterday I am told new evidence has arisen and it could affect the outcome of my claim. Today after 3 weeks of investigations I am still told that the investigator will complete his report next week Monday. Totally disappointed and disgruntled with service delivery from a reputable company as Hollard. When the victim becomes the perpetrator!!
