Webuycars bumped my car - SHOCKING customer service

My car was bumped at the Springfield branch in March while out on a test drive by one of their buyers. We were not in the car. We arranged for our insurance to proceed with the repairs and paid the excess, as well as the excess on the rental vehicle. I have tried for the last 8 weeks to get feedback from anyone at Webuycars regarding a refund - with no luck and lots of frustration. Both the buyer and branch manager from Springfield has disappeared and are ignoring requests about a refund. We have not had an apology. I have called the customer centre about 7 times and was promised a phone call back with feedback. Have spoken to 3 different operators, plus a team leader. I went to the PMB branch (where I live) and the manager tried to help but also seems to run into a wall constantly. @Webuycars, your service has been nothing but absolute SHOCKINGLY bad. No one working for you seems to know who to contact, the legal department is not contactable. I am beyond words about your customer service.
