Regarding the PayPal issue and you refunding...
Are you just aiming this question to those who had paid the first installment, half the total cost, and cannot pay you the final installment due to your PayPal account not accepting payments now?
Or, even to those who've paid the full amount already, 2 installments, do those people need to request a refund too and make the payment via other means?
I suspect the first option but just checking..
I paid the 2 payments already, so I needn't do anything, right?
Cheers
