I’d Choose a bank that is Basel III compliant that will/currently exchange foreign currencies. Just Chill, be patient until the blessing is announced. 
Stop bombarding these bank tellers calling going into banks asking about dinar exchange. Waste of time unless you want to feel ‘important’ & try getting ‘insight’
Just open up an account build rapport & go home and/or If you have an account already
JUST CHILL, be PATIENT until the rate changes on forex & then go into bank to exchange.
You will NOT miss when they announce the new rate. SIMPLE as 1,2,3…
