I need that money reversed

I cashed out money on Sunday as immediate payment and it was successful but it never came through to my account and yet I have to pay that money back I reached out to their whatsapp team since Monday morning and they have been telling me different stories but they were not helpful as I still haven't received the money. SIYA and MONRAY **** to me the whole day yesterday and I reached out to their email support but they are also failing me.
