I have an online shop whose payment system is administered by Paypal. Customers pay with Credit or Debit card or with their paypal account and once Paypal confirms the transaction has been authorised - a few seconds later - the customer receives electronic goods. No problem.
YToday a customer whose goods were sent 5 days ago has mailed me to say that he has received an email from his bank to say there was a problem with his payment and he will try to sort this out.
I have heard nothing from Paypal.
Do I have a problem?
