I tried to purchase the yearly OBC and got this:
However, the money was transferred from my paypal according to recent activity and the OBC was not added to my account.
Not sure if this is just a random error or if this is an error with the site with all transactions. I would like the OBC membership to be added to the account please.
I have also emailed info@roblox.com. The ticket number is 2654210
They can’t really do a lot about it without more information regarding the issue. You will get your OBC, ROBLOX will have 130 Dollars more 
I have put things like transaction ID and the receipt from Paypal in the email I sent
If PayPal rejected it, and money was taken out, you’ll get the money back in (at most) 8 business days. Nothing else you can really do about it. ROBLOX sees that they did not get the money, ergo they’ll send you to PayPal.
Turns out it was a problem on Roblox’s end with PayPal payments. It has been resolved now.
