Individual — Strange call

Address:

Village-Mereli Pathar, (Near MG Model Hospital) PO-Chabua, District-Dibrugarh, Assam

I got call from number [protected] today around 5.56 pm, he introduced himself to be employee of SSBI credit card department and wanted to talk but I denied, he insisted to talk despite of my rejection, I have some doubt, does the bank of credit card office appoint persons to talk personally, I want to make it sure
