Can I use other payment method than PayPal ( it's not safe and I had money stolen by customers, they reported unauthorised transaction and claimed money back from PayPal, when they have got digital products delivered, I have left with negative balance, and have been banned by PayPal, when I reported this robbery at police station, they don't want to qualify it as a crime, PayPal answer is always the same, they don't cover digital products...) ?
