I want to get a refund

Hi, i barely woke up when I registered on the website a few days ago, and “rushed” double clicked when it asked for payment (i thought I only needed to régister to a newsletter to access tje website. I only wanted to see the costs of living in various cities (it was free before on nomadslist.com and I thought it was the same site).

After getting billed I asked a few minutes later for a refund since I won't use its services but the mail adress is invalid. How can I be refunded and cancel the auto renewal.

It's very hard to find. And I dont find any contact info.

Thanks in advance
