Ambank Group — Rude Loan Agent

Dear Sir/Madam,
I am writing in the email to let you know that one of your Customer service/loan agent named: Bhoovinder was being rude and harrased me by calling me non stop back to back on non office hours/weekends in order to respond to his WhatsApp msg. On top of that, he reached out to my brother and threatened to end the process of loan application if i do not answer his call or reply his msg immediately. Why am i being harrased like this instead of be given time to respond? This is unacceptable and the reason why i am not going to proceed with further steps on applying loan or being an Ambank customer for the fear of ill treatment from your agents.
Kindly educate your agents on how to treat customers.
