No Payment to Service providers - Auto Alpina Randburg

I (Reflectionz Auto Spa) was called out to Auto Alpina Randburg to complete a call out for the detailing of a pearl white BMW G20 320d. This was done back in November 2022 and I still have not received any payment from the company after multiple requests for me to submit my invoice to them. I was promised yesterday 07 Feb by Lloyd(manager at Auto Alpina Randburg) thatmy fubds would be paid today and I have not received any payment and now the dealership ia not taking any of my calls. Pathetic service and even more putrid level of urgency and common courtesy for their service providers.
