Songkick is an aggregator of ticket links and tour dates from hundreds of sources. This means that Songkick doesn't directly ticket the events it lists, but rather provides links to buy tickets.
If you click through to a ticket link on Songkick, you're directed to the ticket vendor's website.
If you're looking for help with a ticket you've purchased, you'll need to reach out to the seller.
This means that all support, refund requests, order information changes and payment enquiries must be directed to the seller.
The best thing to do is check on your bank statement or email confirmation for help in finding who you booked with. If you're still having trouble tracking this down, head to the Songkick event listing to find the list of vendors (as shown below).
