Airtel — prepaid recharge of airtel pack

I have recharged to rs.558/- pack for 82 days on 22 july and the credit of same should happen on 6th august 18, but it was not happened and i could not use the internet facility since the previous pack was expired on 5th august. Even i try to recharge with another pack it was not possible. Response from airtel is very slow and they won't even bother about customers. I wasted money on consuming internet directly without a package. I emailed to 121 customer care they told it will be resolved soon by 2 days; again upon inquiry they mentioned a need of another 72 hours to resolve issue.
