I am using Aircel from last 7 years but now I am tired with its poor services.It provide the slowest Internet in Delhi, but I never think to port my number.
But tomorrow I got an offer i.e, recharge with 53 and get 1GB data for 28 days, after I got recharged my number, they provide just 5 days validity and today 49 rupees balance has been deducted and they are not ready to refund my money back. now I just going to port my number. This is the worst network in Delhi, never going to use Aircel again.
