Until recently when I got another new Airtel line, I thought this was a cheat. I did this few months ago and again, recently when others are complaining that it's not working. You can even call Airtel customer care to lay your complaints if you are not given the free mb.
I can remember when Glo was not given me my 200% bonus on my Glo Bumper recharges. I called the customer care, laid the complain and few days later, my accumulated bonuses were credited to my line. That's by the way though now, to the talk of today; getting your free Airtel MB.
