Criminal complaint against a bank collection employee

I have a credit card with 7,000/ limit and now the total overdue is 8400/. Last 6 months I was partly paying my minimum due and constantly in contact with the bank.

I even asked for a payment plan with a fixed amount to be paid monthly. Today a representative called me and screamed at me and even commented about my family.

I want to make a complaint against her and for her to apologize to me.

Please help me.
