Airtel — Talktime recharge with no use.

I wanted to send sms from my airtel number so i recharged with 100 rupees. But stil it show inactive as I haven't recharged with there unlimited pack so I was not able to call or send sms so again I recharged with 19 rupees to activate my services. Then calling and all stuff started but was not able to send sms from my 107 rupees balance so i got to know to send sms you have to recharge with there unlimited plan. So why you have kept talktime plan which is of no use, you are just thugging your customers i cant even send sms though you charge it from my balance but letme do it you crap airtel
