I use a visa card from Access Bank. Everytime i want to pay for a Facebook advert using my Visa card Facebook keeps telling me "Unable To Verify". What could be the cause of this. Other websites allow me to use this card conveniently but Facebook keeps rejecting it. I have contacted Access Bank concerning this issue, all they tell me is that there is nothing wrong from their end. Also someone said only GTB and FCMB cards are accepted by FB in Nigeria. How true is this ?. Gurus in the house, what do you suggest ?
