This is so stupid why would i scam for money that goes on hold and second why would i scam for money that can be refunded WTF is this .... just nvm ...
Your client paid for a service and according to what he presented, it didn't work, why would you sell stuff that doesn't work for starters?
You also seem not to be bothered about refunding him despite his pleas according to the chat logs. So why do you want us to believe that you are not a scammer?
Just do business in good faith and see if people will both calling you a scammer.
