I am also using IOB debit card. Firstly, there is no option for IOB (Indian Overseas Bank) debit cards.
And then it rejects the card - saying something like, "You cannot use that card. Please use another card." or something similar.
First I thought my card is the problem - and seller gets worried, when the buyer says things like I cannot pay, due to .... whatever....
And then on the third day of trying it went through, as a CREDIT CARD! At this point I am totally confused - what was wrong?
And what about IOB makes it some sort of a pariah for Paisapay for Debit card payments?
Get some competent staff, eBay - this is lousy, lazy ... and lousy again!
