Poor Service almost 2 months for a claim

In almost 2 months I get the same story. I submitted all my stuff to them . After that they will not give you feedback unless you call or email otherwise nothing. When you call they waiting for an assessor report .When you call the assessor he submitted it long ago. You call back and then its suddenly there. An investigator was appointed. Then he submits his report without any issues . Then I give them time to do what they need to do. Then they say everything is in order and they just waiting for Mutual and Federal to sign of . 2 days went and same story . Then now sorry they waiting for a technical diagnosis report . This was supposed to be done on the 13th when I checked with the assessors . Then u get treated like a ******** for meeting an accident after 22:00 like seriously !! Then they go against the first investigator report and get a outside company to call me under false pretence. They apparently now accuse me of being drunk and the accident didn't take place where I pointed out. Then they send a 3rd person to verify again. When they want their premiums they take it on time. Now they find ways not to pay.
