if i want to ask for my bank account to be updated what can i say as simply as possible?

Not sure what you mean. Deposit, withdraw, get balance, update your address ? 

i need balance updating

I think he means: balance

yes ...balance please

? Must be a British term. I mean I´d love to update my Account Balance too A transfer maybe?

Anyways I don´t know much financial terms in Turkish in the first place. I was just trying to have the question clarified. Hopefully someone else can help.

Hi Denizli

I have been told today that the word is "bakayesi"

You actually used "bakayesi" at the bank to confirm it works? (If your in Turkey)

Perhaps it may go like this: "Hesap bakeyesi istiyorum"

In case anyone else comes across this and wants clarification further, well here it is: Balance meaning (in this context) is: "How much do I have in my bank account right now".

yes Leo i used this word and they understood in the bank
