The moderators and users of this forum state repeatedly without more information no one can help or offer advice. Is there an ad? What are the full details and logistics of the deal? The buyers contact info? Emails back and forth?
The other party could have multiple userIDs etc. Just "BrandonB5" doesnt say much, without a real name or phone number.
Detail the deal and where it went wrong and maybe you can get some help, often just opening it up here can get resolution.
And maybe if you are lucky its just a communication issue.
Later
