I did that on Tuesday.

What is the problem with processing payments?
I paid for gold membership on Tuesday, but still have basic membership. I last had basic membership when the site was six months old. After a few months or less, I became a gold member. Then, I was a Platinum member for six years, and a Diamond member for three years.
Process my payment, please.
This should have taken place instantly.
