ICICI Bank — emi on debit card, amount reversal haven't yet happened

Few days ago i got this email from icici saying that i can use my debit card to buy things through installments. So i bought lots of stuffs from flipkart, through icici debit card emi method. The complete amount has been deducted from my account now. And it's been almost a week now, the amount hasn't been converted into emi and i haven't gotten the amount back.
Now i have almost no money in my account and it's making me struggle to go through my everyday life. Icici seems to be very careless about my complaint and taking their own time to give a proper response or solution for my issue. Whenever i call their customer care, they forward the call from one person to another and make me wait while doing that till all the currency in my phone gets over. Emails doesn't seems to be helping either. Just crappy automated messages.
I would request icici to not to play around with customers money such that effects their lifestyle in bad way. I wouldn't even had made those purchase if not for that emi on debit card facility. Now am struggling to lead my daily life by trusting icici.
