ARS complete lack of professionalism

I had a third-party claim, The person I dealt with was extremely unprofessional and rude (Bernice). She does not respond to emails and is one sided in their investigations. I provided 2 witnesses to the accident and reported the matter to the police immediately after the accident. After battling for six months to come to an amicable agreement based on the facts on the table with Bernice and ARS I had to resort to legal action against the third party. The accident was a simple case where the driver of the vehicle transgressed traffic laws and caused the accident. Only when I took legal action at additional cost to me the third party instructed ARS to resolve the issue. It was also clear that the third party previously at the start of the matter instructed them to resolve the matter ASAP as they were extremely surprised that the matter was not yet resolved. But ARS deemed it prudent to frustrate the matter, delay the matter at all cost and no will to engage constructively to resolve the matter. Eventually the claim was settled for about 90% of the original claim this also after ARS first made an insulting offer of around 60% which I rejected at further legal costs. Funny thing though ARS deducted 25% of cost of parts from my claim for the age of the car but failed to do so for the third-party car. Very painful and irritating experience. My advice to anyone dealing with ARS and third-party claims is to seek legal advice ASAP otherwise you will be frustrated at all costs.
