Microsoft Store - Zero support with Refunds online Purchase

I am writing to bring to your attention an issue I encountered with a recent purchase of the PDFX software from the Microsoft Store. I uploaded my credit card details in good faith and proceeded with the purchase, only to find that the software does not work on my Android phone, despite claims that it can be installed on mobile devices.

After realizing the incompatibility, I attempted to contact Microsoft for a refund within two hours of the purchase. Unfortunately, I have not received any response. The refund request process on the website seems to be stuck in an endless loop, leading to a frustrating and unproductive experience.

It is quite disappointing to see that after the sale is made, the level of support diminishes. In contrast, I find the refund process on Google Play to be much more efficient and immediate, which is something I greatly appreciate.

Could you please assist me in resolving this issue and processing a refund for the PDFX software? I would be very grateful for your help in this matter.
