Dear Sir/Madam, I also have the same complaint, where I want to bulk block some unknown incoming call numbers at a time when I am free. I called up customer care but they said it is not possible, so I am putting query on this forum to get the data. I am fed up with calls from tele-callers and some unknown numbers, Please provide me with the incomings calls on my number [protected] for last 3 months. thanks...
