The worst service I have ever encountered

This is the worst service I have ever received from an insurance company and their service provide (Targa Auto Body). My car has been with them for over a month now and I have to return the hired car by today without knowing when will my car be ready. Paula from Targa, who is handling my claim is nowhere to be found. if you call her number it's either on voice mail or it rings unanswered.

When I return the rented car, I will be inconvenienced because I won't have transport to travel to and from work. This is the worst service I have ever received. I pay my monthly istalments without failure hoping to get the service I deserve.

Thinking of reporting this to the ombudsman. I have been holding for almost 45 minutes for the insurance company to assist me.

HELP ME PLEASE.
