Mahindra Finance — rude, crude behaviour of mahindra customer manager

Hi sir/madam
Iam lavanya staying telangana at janagoan district
I contact one of your emloyee (Mahender, custermer manager of janagaon branch)
Through phone about house loan proceses he used very unparliamentary language which hurts me alot & ask to pay money more than what they said promised starting of my loan processes.
Its leads stop taking loan from your branch to me
Please cosider my complaint & take appropriate action as per your company norms.
Which will create hope & goodwill of your company in my thoughts.
