terrible customer service

I want to submit a complaint about the poor service I'm receiving from African bank. For 2 months I've been failing to access my account because of fingerprint validation. I submitted the verification from Home affairs and the assistant at my branch has been sending emails to superiors and my issue has been escalated with no solution or response. I'm deeply offended by how this bank treats it's customers because this is money I need soon. What's the point banking with you guys if I can't access my account for two months because of your lack of care. I've been thrown blue ticked by so many people Yoh what a ****ty bank
