ICICI Bank
Constant calling for wrong numbe

For the last one month I have been getting calls every day from ICICI for one Rashmi Mishra. I have told them each time that it's a wrong number but they dont seem to bother to update their database. I get 6-7 calls each day and its extremely irritating. They begin at 8 in the morning and go on all day. I want some action taken against them
