Sorry to interfere in this.
Me myself is a small trader too.

Lets make it clear:

TS is CYYAP's Customer
CYYAP is his Supplier's Customer.

TS banked in to CYYAP account.
Hence CYYAP have to service his customer.
TS doesnt know CYYAP's Supplier, even so the SUPPLIER can deny saying received any money from TS.


TS has the right to ask for a refund.
AND NO, the refund shouldnt be from the SUPPLIER.
IT HAS TO BE FROM CYYAP HIMSELF (stop saying SUPPLIER refunded and all, thats all BS. if so, mana record?).
How CYYAP get the money, is non of our business.

TBH, dont drag your Supplier in here.
because TS deal with CYYAP. its a 1-on-1 business agreement.
as he might be "Fictional" supplier created by CYYAP.


if your Supplier is real, you should lodge the police report against him.

if all these 3 people lodge a police report on you (provided with the bank transfer slip etc), the conviction goes to you, not to your Supplier.
even if you 101% cooperate and they couldn't find the Supplier or couldnt solve the case.
who will it ended up to? YOU.


Easy money as the middle man? there's no such thing.
Work hard, get your contacts. Deal directly. X-Stock then only be a trader dude.
any PRESALE sales is all BS Scam (mostly).

I'd say;

1) give him a deadline to reply.
2) layout a timeframe for refund.

failure to do so, all 3 go lipot.

case close.

money fly de.
he go in.

dont drop the soap.
