Claim taking forever

On the 12th of June 2020 my car was taken to Nissan/Renault Menlyn. The correspondence that I have in writing shows that the claim was made on the 18th of June. By the 22nd of June the claim was still not processed after I had to phone msure myself to see what was going on as there was apparently no communication from them to Renault. Today on the 25th of June I phoned Msure again to follow up. Still nothing done as they say they need more information. I've been copied in to all correspondence and they have all relevant information. It's now been two weeks without transport and I am quite frankly getting sick of this. I will never, as long as I live, recommend Msure to anyone. Even here on hellopeter you can see their abysmal ratings
