4 months to get paid for accident caused by there client

In June a client of Constantia Insurance bumped into the rear of my car - From then till current they still haven't paid me out. They never advised which panel beaters to take it to, they have not contacted me. You don't get through when you call!!!!! my car was being traded in the very next week and I had to pay for the costs. To date I hear nothing - there staff are so unprofessional and not interested in helping . I work in a dealer ship and will most certainly never advise our customers to use this company. Shocking
