Consumer Redressal

I am using Airtel No 8427424366 since last 18 months and when i went to purchase another post paid under same corporate I was told by Airtel store at sec 22 that mine corporate mapping is wrong in system and i have to submit fresh documents and first purchase new prepaid sim and get it converted to post paid under same number and it was done on 09/06.On 10/06 i requested at call centre for change of post paid plan from 125 to 199 and it was done and confirmation message was recd. After this my number stopped working and i was informed by call centre that no. Has been converted to prepaid by airtel store.On visit to Airtel store they provided me with another sim but number could not be started. Today i was told that mine number has been changed to prepaid by parkash kaur at Call centre without pairing sim that’s why mine number cant be started Today I was told by call centre that mine no.has been closed.I am surprised to know that how mine no is closed NO one is taking the responsibil
