Pathetic service

Was involved in an accident 29 June taxi was driving in bus lane and knocked my car on drivers side and been battling ever since, first agent Yvonne who never contacted back and every time I call in there is something they need and now I've been dealing with Roxcal since late July and everytime I call in there is something she needs for me to send, if I don't call in then they don't call me unless I complain about it, I've been told for the past 4 weeks one last step then it's complete, I have even got to the point and collected my car from storage and paid for the release to start repairing myself and i am still waiting for them to resolve the complain.tried logging a complaint with complaints department but Roxcal says it's no use because it just comes back to them to handle.they dont consider the inconvenience in them delaying its been two months and for an accident i did not cause this is unacceptable, and in my profession i need a car now I have to ask so many people to assist and has been causing them inconvenience and it is costing me had enough I have been cooperating with everything they asked for and I need help solving this claim please. My claim no is. CL ********** 13
