Paypal payments are handled daily and in real time, money is sent and received every day, it is not a bank that closes at the weekend.
I recieve payments from other hosts in weekends as well and recieved it from openload in the past. Besides, I've requested my payment on Wednesday and it's still pending.
I know that I will receive my payment, it's not a doubt, but I chose openload to receive it quickly within promised 24-hours, which in fact, is no longer valid. That's why I'm requesting payments in advance to get them before the weekend because I know they have delays and yet they are not able to process it.
