HDB Financial Services — Abusive language and a disgrace

Hi HDB,
You executive Mr Rahul[protected] called my mother and used abusive and inappropriate language and I spoke to him and have recorded the call as well which I'll surely share on social media and will file FIR as well. He was calling me for my relative who has taken and hasn't repaid it. So what the ### we can do if you want you can go to his residence or submit a police complaint against him. Who has given you the right to call some other person and abuse him constantly.
