Terrible experience

I recently immigrated to Canada. End of January, I contacted FNB to ask them to change my bank account end of February to a Pay as you Use account. I followed up again beginning of this month. This morning when I woke up, I saw that you have charged me for full bank costs? How ********* is that?

Ive also requested all my personal details to be changed. Ive received an automated response stating that the request is concluded. Does this mean someone closed my request without actioning or that it is actually done as we havent received any notification?

Lastly, Ive asked someone from the credit card division to contact me. Again, I havent received anything. As I am out of the country, I would prefer email as with time zones it is difficult. Again, it fell on deaf ears.

Do you guys have something like customer services? I wont be paying these extra fees charged and will be taking it further.
