[Resolved]  Kotak Mahindra — Usage of abusive language on solicitation calls

Hi I work with a big organization at a Managerial position. I have been receiving SALES calls from Kotak Mahindra from number [protected]. The guy calls up and asks for my name and other details and tries to sell insurance policies and Personal loans, when asked not to call up my number, they start using abusive language. It is really frustrating they call from the same number and it is really frustrating can some one help?
