No doubt it’s Paypal! I keep having the same problem when they debit my Website Payments Pro monthly fee. Several times the payment has been rejected even though the money is there. I spoke to my bank and they said it was Paypal. Paypal were no help though, they believed it was the bank’s fault. I have to say I believe the bank as they said there were no account restrictions and the funds were readily available.
Thank you to everybody who has purchased or promoted my files. Reached 100 sales, looking forward to the next 100.
