how did you find out you were scammed? Maybe you can give advice to stop others from falling in this predicament.
Advice for the future- check out the website to see if its reliable before sending the money. No credit card- they wanted western union? That sounds kind of iffy….
Advice for now- contact Western Union. You probably lost the money but you never know… I have never used western union so I don’t know what their terms and fine print are.
