Airtel — recharge for mobile requested on www.statebankrewards.com on 21.9.2017 - not yet recharged - reg.

I had reward points on www.StateBankRewards.com and utilised some points and paid the balance amount in cash through sbi net banking towards recharging of mobile on 21/09/2017. Surprisingly, the mobile is not recharged till date. To-day i have verified my account to see the details of past redemption. It is not shown either success or failure. It means i have lost the amount paid in cash and also valuable points. My second complaint is that when i am sending sms there is a deduction of rupees four from my balance in the mobile. The screen is showing sms cost rs. 1 but the balance is being reduced by rupees four. Why this is happening is not understood.
