ICICI Bank — Deduction of Money from a/c through ATM transaction

I was withdrawing money from nearest ICICI Bank ATM to my home though careless cash withdrawal. After all the usual process, ATM asked to write exact amount, so wrote it. Then a Norma cash withdrawal sound was there clearly geared, but no cash were at the exit of machine. And ATM was showing that it is temporarily unable to dispense cash...but that money was deducted from my account in the next moment. And I am so tense, so please help me in this regard. I tried to call on 1800 1080, but number is showing to be invalid. I don't expect this type of blunders from a reputed bank like ICICI. Please help me @icici customer care!
