Bad service

I received a terrible service, I honestly beleive it when people say MIWAY is a ****. My dad was involved in an accident in March with a MIWAY client, the client agreed to be at fault, she told us she lost control. We claimed to MIWAY as a third party, we got assigned a legal advisor to handle our case, everything was going okay, kept all conversations via emails. Then the legal advisor who was handling our case said everything is in order they will soon send me an offer, everything is finalized they will pay(all this is in email as proof). As we were waiting, all of a sudden the person who was handling the case left the company they now assign a new person. The new guy ddnt know his story, one minute he says he hasn't looked at the file, the next he says the previous legal advisor made mistakes, so he is trying to rectify then all of a sudden within 10minutes he send an email of 'Refute'. I asked how because 10minutes ago you said you haven't checked that case file, and the previous person said they going to pay out and every thing is finalised and I have that as a proof. And he honestly just said they closed my case, without even answering all my questions. He says the lady hit the pot hole, which is not true because on accident report there is no such. What is heart breaking is that, this was a business truck, my dad used it to work, now he cant provide because he doesn't have a car to work. Firstly, they gave us false hope by saying they going to pay, secondly they blame their own employer whom they appoint to handle the case and I don't understand how is that our problem. Thirdly, they do not respond when I show them all the proofs from emails. Yoh! It has been full 6months.
