The worst Pannel beaters ever

Terrible service and workmanship. When I booked in my car I was promised that the work will be done within 2 to 3 days and which never happened. They do not communicate at all. Each time I called, I was told that they will get back to me which they never did. The receptionist was rude and I am traumatised. The quality of their work is so bad. The bent parts were not straightened. The paint started cracking a week after collecting my car. I have sent several emails with pictures of the work and they are not responding. I am too traumatised to call.
