Windows 10: Roblox robux purchase not working!

Hello! Today I was trying to buy some robux 10$ and it didn't work! I did that and whenever it finished loading... It said "Your Payment Has Been Cancelled. I did it more and it still said "Your Payment has been canceled." It didn't take my money away or anything. I made sure the cards were right and yes, they were right. Any Answers?

Problems with robux purchase

I bought robux but It didnt add to my roblox account (Im playing on pc) can i not use it on pc?

 

Where did my robux go?

Hello,

I have recently purchased robux from the microsoft store, but when I went to my account, the robux wasn't there.

Then, i realized that i was on the original roblox website, and there must've been a roblox from microsoft. Surely enough, there was. But, when i checked my balance again, there was still no robux. Then, i thought that the email i used to purchase the robux
had to be the same email as the account email, so I went over to my profile, and changed my email. But, the robux STILL wasn't in my balance. My final thought was, i had to go onto the Xbox to find the robux. So, i made a completely new account, joined into
the game, and there was no robux.

I spent around $50.00 worth or robux in the purchase, so could you please tell me an answer on where i can find my robux. If possible, if there was a way to refund robux, please let me know.
