Airtel — my inactive sim card

Address:

600034

Dear sir,

This is areeb ali bazaz, my airtel number is [protected]. I have purchased this number in 2012 june or july. Recently i have landed to singapore in february 2017 and since then till date 19 september 2017, my number was switched off. I want to use my number and it is stating it is not active. This number was purchased under the name of my uncle "gopal krishnan" at that time for me. Please help me to activate this number as this is the only number of mine which i have in india. This is the only number which is registered under my bank account.
Kindly do the needful. As i have used this number for more than 4 years.
Thanking you!

Regards,
Areeb ali bazaz.
