Horrid service!

I was in accident more than 2 weeks ago. Claim number *** and it was referred to Proline Panel beaters. Up to now I have not been contacted ONCE by A&G and I have to phone Proline panel beaters for any updates. I have not received a single email from either parties. Proline keeps on giving excuses and I am still without a car 2 weeks later. Nomti from Proline has been trying but I am not satisfied. Keeps on promising Manager will phone me in 5 minutes. Whole day later and no call. I was impressed with A&G straight after accident and the it stopped. Have logs of numerous calls trying to get ahold of A&G today, just hear their horrific music and no response. I am tired. I pay my insurance installment every month yet I receive NO service! What do I do?????
