GrimeFighter Refund - no response to support request

Hello, I’ve had no response to my support request so am posting on here to ask for a refund as GrimeFighter will not work on my PC (cannot recognise WiFi or physical connection). It would be much appreciated if my refund request could be expedited.

Ticket ID: XCQ-497-63104

Thank you
