I know how charge backs work and I know about Entro-Pay in-depth. The merchant will get a letter in the mail stating there was a charge back they have X amount of days to submit evidence it was a legal purchase. I have had nothing but 100% positive dealings with caradenada in the past for 1000's of dollars. None of them have been charged back and he has provided every piece of info I have ever asked him for. I do not think he defrauded you, cause of prior dealings I have had with him and he had a way greater chance to make lots of money off of me.

How fast after you purchased was there a charge back claim? Days, weeks, Months?
What kind of business was it and did they know it was a entro-pay card before you used it? "This does matter"

The merchant should be able to go right into his Merchant account and pull the Charge Back up with the Ref # Date and Reason Code
^ This is what you need to show to prove this.

Would you disclose the merchant that this happened with?
