Airtel — Fraudulent act/poor service

I am K Kolappan, subscriber of airtel
mobile no. [protected], Tamilnadu circle, would like to bring
the following for your kind judgment and action.

On 8th Dec. I received a SMS on this line stating that the
line has not been used for more than 90 days and hence to
recharge my line within 15 days to avoid suspension of the
line. Though I have tried to recharge couple of times, due
to system problems I could able to successfully recharge on
20 Dec. an amount of INR 50/-. But when I checked my line it
was showing "SIM card registration failed" message. On the
same day I contacted customer care and informed about the
same. Subsequently Customer care asked few details and that
too provided with a request to activate my line immediately.
Surprisingly I was told by Customer care that my line has
been permanently disconnected on 13th December, which is
well before the 15 days period given to me. In my several
further follow-up with airtel, they asked my alternate
number so that they will call me to resolve the issue.
Though I had given my alternate numbers they never called me
and instead later they informed me that the line has been
reallocated to other customer. Later I have sent many
reminders, but airtel is not responding. hence I request
your intervention and appropriate actions in this may help
millions of customers who were becoming victims of such
service providers.

Here my concerns are summarized as;

1. Why did airtel disconnected my line on 13th Dec., though
I have recharged within the given 15 days time...?
2. If my line was disconnected on 13th Dec. (as informed by
airtel) how could it accept the recharge amount...????
3. How could airtel allocate this number to other customer,
while my issue is pending???
4. Why airtel didn’t call me to settle the issue….???
5. How can I utilize the pending amount in the line…???
6. I am loosing all my communications/bank
alerts/notification.etc...to which airtel to compensate me
INR 1000/day from 13 Dec. until the line is activated.
