The problem here is that the scam report information is of public access. Anyone can enter the scam report and copy it on another forum.
He sent you his address on the chat in your site, and posted the same address on both OGU and here. You could have checked this before processing a refund to a new profile that clearly was made just to report you. This profile was an impersonator.
The refund was not properly processed, and this is not the buyers fault because he sent you the address privately before making a scam report. You had the information available to you and chose not to use it.
How would an impersonator link an image that has his exact profile details on our site and additionally explain the same issue. We have plenty of site logs that completely contradict what's being said, much of which I've provided.
I understand your reasoning, but it doesn't match up with what was found through our logs and investigation of this matter.
Additionally, this whole report could be disregarded by the fact that after further investigation, this user was reselling our Datacenter proxy product which we prohibit and will terminate users that perform these sort of actions. We have a no refund policy for users that use our proxies for prohibited use cases. Reselling is only permitted for our ISP proxy product.

If you disagree, feel free to ban my profile. No hard feelings.
