ATM machine surprise me yesterday as I needed money since my bank (GTbank) is a little bit far from where I stay,so I decided to use UBA ATM. I slot in my card ,type all necessary details and waiting to collect the money.What I saw was I can't withdraw money at this time.I brought out my card and I alert came immediately from GTBank "The amount of N5000 and N65 service charge has been deducted from your account. I rushed into UBA bank to lay my complain ,the security man at the entrance as I explain to him told me that it was my bank's network that caused the issue. So I went home,waited for a whole day to see if the they will reverse it to no avail.
This morning,I went to my Bank (GTBank) and complain to them, after filling the form that they gave me, I was told, it will take 8 to 10 working days(2weeks) before they can reverse it.
This happened at Aba Owerri Road,Aba,Abia State.
I don't know what these our banks are turning into.
I should wait for a whole 2 weeks, to get my money back.
Let me stop here for now.

It would be reversed.
That's normal procedure, except you show them some kungfu style. E.G Slap the Branch Manager when he is trying to tell you calm down

The discrepancy is not necessary particular to Nigeria bank or ATM. I have same issue with HSBC bank ATM Europe & it took 24hours for it to be reverse and when i had same issue with Zenith ATM on a GT card, it took 21 days for it to reverse after much pressure.
