[Resolved]  Airtel — network registration issue

I've recently port my no. From voda to airtel for the plan of 499 i insert the sim in my 4g handset it got activated i even made a phone call next i insert the sim on my 3g handset as the previous handset is broken, it is not registering to any network i went customer care centre they charge me 25 rs and alloted me another sim said that it would get activated in 4 hours its been 24 hours i'm still facing the same problem with the new sim to. Guys u r setting a bad example i'm new into ur network before starting even i already have to change 2 sims n it isn't working yet from 3 days i'm facing this trouble no phone calls either uh fix my problem or i have to choose some other network no other choice.
