Toyota staff involved in accident with company car

I was in an accident with this person on 16/07. Venessa is liable for the damage done however I am now in an uphill battle to get any information. She and the manager of the branch are very unhelpful they are requesting bits of information and not confirming when my car will be fixed. I have on numerous occasions asked for this and have received no response. Venessa is rude and unhelpful.this is the car I use for work i have no transport and am battling to get to work on a daily basis. I am shocked and appalled at this behaviour as I would have expected them you be helpful and upcoming with insurance information. I am now stranded with no car and getting no cooperation from them.it was a company vehicle that she was driving. I have sent through all my details I have received none from her and claims to not know which insurance company the car is insured with and head office is handling it.they have kept cutting the call on me and no one is responding. I need the use of a courtesy vehicle as my work is in jeopardy which is my bread and butter and I have no means of transport
