Fnb complaint by Khadijah Joyce

My name is Khadijah Joyce. I'm currently working abroad on a cruise ship. My phone broke and I had forgotten my password to my fnb app. When I tried to reset it I got blocked out of my account and had no access into my account. I've sent an email regarding this to fnb and they havent been giving me a speedy response. When they eventually responded they requested me to fill out an international form. I've filled this form out and now I haven't gotten a response at all! I'm very upset because there's a delay for me to pay my account and it's making me look bad with credit. I'm so frustrated to not have access to my account. I need this to be fixed as soon as possible. This is unacceptable. Please help me kind regards Khadijah Joyce.
