Abusive language and harassment used by collection agent of a bank

Hi,

Can I file a complaint against a debt collecting agent for harassing me to collect my debts for a bank in UAE?

They have been calling me and I responded to their calls and during my off, they tried to reach me but I could not respond to them due to personal reasons.

They called my parents back home and threatened me saying they will call my boss and sent me a voice text saying "I will make you suffer".

They are using abusive and unprofessional languag like "I am criminal" and "liar" and asking me "Am I a human even?".
