Well, waiting for 3 days is still a bit fair if you ask me, I don't know but at times, some people has or had to wait for a week or more before they get their withdrawal request finally processed, this happens mostly when the wallet holding funds for users requesting withdrawals goes empty and is taking a bit of time for them to get it refilled.

But all the same though, this is not me defending the platform for not processing users withdrawal request on time, I have joined in advising users to stop depositing new money to the site, but rather make do what balances already on the site and ensure to withdraw the funds when the opportunity arises.
Hopefully, they will arise to fix the site when they see that no new money is being deposited to the site any more.
