But no use, they just ignoring my words and keep on calling me every day. I am really getting mentally disturbed with this phone calls. I started blocking there numbers but everyday they are calling me from different numbers. So, there is no use of blocking the numbers. I even said i am going to give complaint against rbl bank but they are not minding my words.
