Claim taking long to finalize and car stripped

I put an accident claim on 2 March 2018 and Old Mutual Insure kept dragging the claim until 24 May 2018 only to reject claiming that I didn’t disclose that I had a previous insurance. When I took out insurance with them they never asked me if I had an accident, they only asked if I had a previous insurance which I told them about. They are refusing to give me call recordings when I took out insurance. They took me from pillar to post to reject the claim. They were just looking for a reason to reject, how can a claim take almost 2 months to finalize? When they are debitting your account, all is good but when it’s time for them to pay they find excuses. And they towed my car from my yard to their Panelbeaters and after rejecting the claim they said I must go & fetch my car from SMD Chamdor & they will not tow it back. Bear in mind that if I do not tow it, SMD will charge me storage. When I got to SMD, my car battery was missing & when I reported it, they started stripping other cars to replace my battery. I do not know what else is missing from my car. Our cars are being stripped while in their hands.
