This is inform you that I am really disturbed by Airtel calls unwanted calls I mean its crazy to call customers 25 to 30 times a day!! My number is 9663480881 and I really want airtel not to call me. Its very much annoying! 25-30 times service calls a day crazy or what! Just look to the matter don’t disturb customers like that Its not acceptable at all ! I want immediate action to be taken! I hope Airtel is not providing service to disturb its customer!
