Sorry bud you've probably been scammed, eWallet is the scammers choice, that should have been an immediate redflag.
I bought some eBucks from a guy who had joined Mybb pretty recently and had a low post count. I told him I would only buy them if he first sent the eBucks, which he did and then I paid for them via eft. That was what I was going to do with the op if I managed to get to first in line.
Eeish not nice to hear, hopefully I'm wrong and the op comes through.
But another telling thing is the op switched off PM's, which is weird for a new member to do and also a hallmark of scammers because they always want to immediately take the conversation off forum.
How did the op contact you to get your WhatsApp number if not via pm?
