Airtel — misguided through customer cafe

Sir, i called three days ago to customer care and ask about the hello tune, mam said me that there is a plan of 299 for one year and i said him yes. He requested me to recharge immediately. After some time i again called to customer care but now she misguide me about the recharge of (115 full talktime) she said me that the money was deducted from your direct account and recharge.
Then i recharged with 115, 115 and 90 now i had enough money for hello tune charges (299)
But now he say me that the money is not deducted from da
Then what can i do with that 230rs. And the validity of these money is only 10 days.
