7 weeks car in for repairs. sluggish progress.

Car went in for rear and left rear repairs in March. By early second week of march the claim was authorised. It took over a week waiting for parts-VW parts!! I must call everytime to ask about the progress. I've even exceeded the 30 days claim for courtesy car hire. Hiring from my own pocket INDEFINATELY. I call numerous times to ask about progress no answer. So called personal claim agent always needs to go see car for progress indicating her lack of awareness and interest in her client's vehicle. Still without my car til this day. Phones unanswered. Paying for hiring a car. Til when? Substandard service.
