Based on 2 experiences so far with first bank mobile app on android. I will advice qw think twice b4 doing any transfer.
Oct 2nd 2015 I transferred 20k to my uba Acct. I was debited but was not credited on my Uba.
Same thing happened again yesterday and all they can tell me is I must have mistakenly chosen a wrong account. Then a wrong name and a wrong bank.
When no be sleep will one not know with those things coming in stages.
First mobile is fraud!!!!!

Although I have never used a mobile app for my bank transactions but I think first you need to check your details properly first before doing any transaction online. Keep in mind that you are not the first to use the app. If they have encountered such problem in the beginning, defiantly they would have solved it. And lastly, check your UBA BANK account transaction details via the bank. I had same issues but never knew it was a network problem.

If the transaction was done to another account they should at least provide the account details. Moreover, there should be an email notification that will contain details of the transaction.

That's d problem they have not provided d details of d recipient. When it happened before they claimed the person has withdrawn d money.and they have flagged d acct to auto lock any further cash lodgement.
Till date no news

Also the application ask bank then account no after which it displays d account name.
If one makes mistake with account no will someone not recognise the account as a verification?
Haba.
I suspect either a hack or a mole .
Then whichever the account the money goes to should be checked too. It might give a clue to who is really behind it.

I still await first bank response to all my request via mail
