Airtel - International Roaming Charges refund

I have bought a new connection number ********** on saturday dated **/**/****. After the FRC (First Recharge Coupen) by Airtel dealer. I have done a recharge of ****/- on dated **/**/**** at about *:** PM. the last talk on this phone was at **:** Pm on dated **/**/****. but after that time there is no incoming and outgoing calls on this mobile number. on monday **/**/**** about evening time I have talk to the *** executive about this international recharge he told me that there is no recharge like this and the money might be deducted from the account but late in *-* days it will be refunded to you in your account. then I done another recharge of amount of *** Rupees on this number again for one day international roaming. but the after that again there is no incoming and outgoing calls on this number. I try to call *** assistant at evening time about *:** PM on **/**/****. I talk to the senior executive also but they didn't solve my problem about incoming or outgoing calls on this number. they told me to call back in within ** minutes to my mobile number. but did not receive any call. after ** min. I called them again but after a talk of **-** minutes they put my number on hold and cut the call in between. so i please request you to please look in this matter and refund my amount as I am not able to receive the benefits of International Roaming Recharge of Rupees ****/- and ***/-. on this number. After two days I send a mail to the nodal officer airtel and tell them about the issue. He called me back and told me that he will do some thing in this matter. On dated **/**/**** the nodal officer called me and refuse to refund my money in my account
but I did not expect this kind of behaviour from the Airtel Team. so please lodge my complaint against airtel.
