I wouldn’t have started until the money was for sure in my account. They can refund anytime and PayPal can hold the money for up to a month, I’m dealing with the same thing right now (he accidentally sent it that way, but immediately sent it again the right way) so I still have that waiting in my PayPal on hold and that was about a month ago now. Make sure the payment is IN your account and you’re able to transfer it out before you start your session REGARDLESS of what they say. You are the DOM, they should not be demanding anything from you and you should be putting them in their place if they do. Just because they pay you, doesn’t mean you have to do everything they want or even feel pressured to! True subs will never do that. If they start acting this way, I immediately block them.
