I've discussed the circumstances of this with @Amir, & have seen the messages between himself & @HallyMadd, including him asking for payment via f&f, which as we all know is a massive red flag, thankfully Amir had the sense to pay the fees on g&s, so should get his money back.
While I'm not ready to brand Hallymadd as a scammer, he now has deserved negative feedback which all potential buyers need to be aware of, he took payment & sent nothing, despite repeated polite nudges from the buyer.
NEVER do f&f unless it's someone you know & trust implicitly, & even then only for very small amounts, as any issue in the delivery chain could cause you to lose your money.
