Hi, I want to post here after signing up for ole7.io yesterday.
I made a deposit of $500 as seen here
https://etherscan.io/tx/0x914039e722ea975758d4f4115c71f880e9e6c1ba4297be237dab0e034b877ca0 but my deposit never arrived, so after a few hours I contacted support and they said wait up to 24 hours, which I have.
I received the email below.
I don't know how I can give a receipt from the exchange app as I sent the money from a wallet saved on my computer.
I'm still waiting for my response as I've stated there is no 'payment confirmation receipt from the exchange app'.
I've bet on many gambling sites and this is the first to withhold a deposit and make such a weird request.
I'll keep my post updated as things progress, but my caution right now for anyone would be to not deposit on this site.

As a way forward to resolving your complaint, I suggest you follow the guidelines accordingly so as not to be tagged a defaulter because no one can tell anymore from the complaints so far on their announcement thread and I hope you did your kyc and scaled through successfully if truly there is any option for kyc because that might be another factor too if they have such policy and makes it a must requirements before getting onboard their platform. In respect to the receipt, i would suggest you send the link or transaction hash to your deposit with them and possibly send or attach a screenshot of the transaction to back it up as a proof that you did made a deposit with them.
This is my solemn advise to gamblers, bettors etc. Do well to read the terms and conditions, privacy policy as well before you get engaged with casinos so as not to get entangled along the way while trying to use the platform after making deposit or withdrawal. It would be for your own safety that you do a clean Research onboard this platform before getting involved with them.
