Idea Cellular — Unnecessary disturbance

I have recently stopped the irrelevant calls which i was receiving from idea phones under dnd. Today again i received 3 calls in an interval of 30 minutes from one madam (Name not known) to my idea no [protected] mentioning that i am using their no very less as i am suffering from fever for last 2-3 days and was sleeping (Bed rest) after taking dr medicines as per his advice. This is very wrong on the part of idea people. Can anybody tell me why it is happening by idea.
