renew- it greenstone

I had a small damage on my car, front left. My insurance sent me to Renew it in Greenstone. I have heard bad experiences about them and bad reviews on your site but I was rather hoping it wouldn't happen to me. Wishful thinking! They kept my car for almost 4 weeks ( the spares were delivered two days after I dropped my car) which already was unacceptable only because i complained bitterly , I think , I got it faster than others. BUT not only the paint on the bonnet is slightly damaged for which they want me to come back ( somebody must have touched it while it was still wet) but my left front door squeaks ( I think the bonnet is too close) and I have a small dent on the right side below the bonnet. There is no way I will bring my car back to them as they have proved that not only they do not care, also the workmanship is not up to par and above all no quality control. The only thing I have to say which is not bad was that the assessor/ customer service was friendly and really tried to help me.
