Axis Bank — Unwanted phone calls

Address:	600040
Website:	www.axisbank.com

I created a salary account in Axis bank recently. Ever since that, i have been getting calls from many Welfare Organization asking for donations.
What i like to know is why does the bank publish our phone numbers to these organizations without informing us.

I have also been getting calls from bank asking to get Credit card. I already told them not to call me and add me to DO NOT CALL registry. But still it is happening.
