I would strongly reccomend Alper at Fortis bank, he speaks excellent English, he gives you his mobile number, if you are watching rates to change money he calls you to keep you informed. The Sunday before Bayram I used the ATM at Fortis and it swallowed my card, the strip was damaged.
I sent Alper a message on his mobile to ask him to get it for me when the bank opened on the Friday. He called me within 2 mins to check what had happened and which ATM I had used and if there was anything suspicous. He told me to check my account on line ( Fortis internet banking is easy to use and all in English)and call him if there was any activity and he would call customer service and cancell my card. Everything was ok but it is nice to know that someone was prepared to help out even during his holidays.
