Dear customer,

Mila, ChangeHero team
Hi, thank you for accepting my invitation and presenting yourself here. If you don't mind, can you explain why OP's KYC need 48 hours to be verified while your ToS specified it to be --you said and I quote-- up to 24 hours or less?
You are right, something is not right about their service and they are ignoring all questions, whereas they are coming online and lurking around.
I wouldn't conclude that fast. Yes, ChangeHero made a questionable decision when they ask for 48H verification process while they agreed it will take 24H or less on their own ToS, and thus contributing to OP's clouded judgment and added more fuel to his burning bright FOMO. But, OP is not completely not at fault here, they shared some degree of blame.
As stated, they've agreed and gave their permission --ChangeHero asked prior to executing it-- to cancel the buy order with the penalty. The rule was explained on their ToS and suppose OP did not read the ToS, it was once again made clear by the customer service during their exchange of communication.
It might be worth to mention that OP also didn't bother to wait for ChangeHero's response. Their last online time was few hours before ChangeHero's reply. If I may pull out an assumption here --other than a possibility that they wrote this thread with alt and monitored the development of their case through their main-- they might finally got out from their frustration and acknowledged that they shared a blame, thus didn't pursue this case any longer.
