No money came back within 7 business days.

Hello. I cannot write to the support service in my account, it shows me a mistake and offers other options for solving the problem.

I paid for the service 50 $ September 23. I was charged again 50 $ for the service on October 1. I wrote in support after this and apologized for the inconvenience. They said that the money will return after 7 working days. But the money never came. Why?
