Airtel — stopped the incoming and outgoing service

Address:

Solapur, Maharashtra, 413304

Repected sir,
My name is mr sandeep prakash kale
From pandharpur dist solapur, maharashtra pin 413304.

I purchased airtel card 2006 and my airtel number is [protected].
In 2006 for 12 months i recharged rs 99 for every month to get life time validity upto 2032. (This scheme was sponsored by airtel at that time)
I recharged for 12 months (99 * 112 = 1188 rs) and i got lifetime validity upto 2032.
But for last few months airtel has stopping my incoming service due to zero balance and it showing validity dare feb 10, 2019 and forcing me to recharge airtel of rs 38 or etc..
So kindly solve this issue.
