Airtel — portability cheating

Address:

Bangalore, Karnataka, 560032

I needed to change port and so I went to the Airtel office and they said that they don't have sim stock 3 to 4 times and later after 1 week when I went again to Airtel office, they said that I am using Airtel number, (changed port to Aircel four years ago), you need to go only to postpaid because you have come again to Airtel and misguided me and forced me to take postpaid and they booked my number to postpaid and took 300 rs as charges and told to take 499 plan. There is no policy that we need to port to Airtel only with postpaid plan when you are using prepaid plan. This Airtel office is located in CBI road, ganganagar and their executives are misguiding and cheating people. Please take up action against them.
