[Resolved]  Aircel — No response for application submitted for migration from post paid to prepaid

Hello,
I had submitted application for migration of 4 aircel post paid numbers to prepaid. Nothing was happening. I had to call call center, walk to customer care center, velachery and post emails to aircel appellate authority, almost on a daily basis since 2nd February, 2017. (my application for migrating all the four numbers was submitted on 26th Dec 2016). It was after a lot of harsh talk, that two mobile numbers were migrated. Bothe the mobiles went dead for three days. Only after constant prodding and yelling, the mobiles were activated. And I had to continue the daily process of making calls, meeting customer care, and emailing and one more number was migrated. One number is still not migrated and I have been talking and emailing almost on daily basis. My emails to talkaircel and aircel appellatate authority are auto responded, which state two days time to settle my grivance. The two days' time has never seen any action or further emails. I was asked to make payment in advance for 15 days post paid service, promising my numbers would migrate within that period, which I promptly paid on the same day, 26th Dec 2016.
It is pathetic the manner in which aircel treats its subscribers. I am not alone in feeling this was; I see a lot of people at the customer care, grieving and yelling about the irresponsible attitude of Aircel. I am wondering what are the options left to me as an honest subscriber, to get the remaining mobile number migrated. Would you suggest resorting to legal action?
