3 - 4 Months - No repair progress

I am having the worse experience with PMD car insurance, this is the 3rd month since my car has been in for repairs and I have not received it. Miscommunication between repairer myself and PMD. there's no update whatsoever I have to phone them for an update I even launched a complaint with their complaints department but nothing has changed in the status of my vehicle. This is the worst insurance company I have ever used, this is my first claim in 6 years with this insurance.
