Pathetic service

I have been moving back and forth getting quotations and sending photos of my vehicle and after 2 months of all the waste of emails and calls I'm told my claim is disregarded because your insured says it's my fault the collision happened. The first statement she made she acknowledged that she bumped me that's why we even started the claim. If I was at fault I could have never asked for her insurance to help me and she also could have made a statement that she did nothing wrong. My case was with 3rd party and also sent to an assessor and it was then taken to a Negotiator by the name Moosa Nabbie who has been handling this case for 17 days and he also kept asking for more documents and I did as he wanted and then he kept on taking pillar to post so I then complained about his service and there after he started to help me. Today my claim is declined because of a statement their insured issued saying I was in the wrong but I ask myself why I had to go through all this if I was wrong?? Moosa gave me a rotten service and he made sure my claim fails because I complained about him. I wish I had the resources to sue Old mutual for this nonsense. I will revert back to your insure and give her the car to fix since she chose to lie to you,me,police officer and traffic officer by saying she bumped me and her insurance will cover.
