Hello Rocket23,
Well, let's see now.
- Is this your first time with the issue, or have you had this issue before? have you contacted the bidder?
- How patient are you in waiting for payment?
- What is your selling venue? From looking at various (well-known) websites, there usually is a time frame to pay. eBay for example you can file a report after 2 days and the buyer has about 4 days to respond, with a maximum of 36 days total.
I usually give a week to pay. People may have other higher priorities ...
