Shocking service from Car Trawler

Very poor experience with from this company. Booked a car through them in and paid in advance. When we went to collect at the car hire company they refused to provide the car. We then fortunately got another car from a local competitor car hire company at our additional cost. When I afterwards wanted to get a refund from Car Trawler they delayed with every tactic and kept me waiting for over 5 months of unnecessary argument and frustration. I will never deal with this company again
