wrong deduction of balance

Location/place: surat

Name of company/service: tata docomo

sir aaj date 4/7/13 laghbhag 2 bje mere mobile me approx 160 balance tha aur 100 se 150 mb 3G data tha aur mei google play store se free game download kar rha tha jo 60 mb ka tha….
kuch der me aadha download hua hoga tabhi mera 158 balance cut ho gaya aur 3 m hi rahha….
tata docomo ke customer care pe bat ki to unhone mera refund dene se mana kar diya……
mei aap se request karta hu ki aap jaldi se jaldi is problem ka sollution kijiye aur mera refund dilvaiye….
unka kehna he ki mene koi chargeble site open ki thi jab ki esa kuch hua nhi he….

thanks
