IndiFlashMart - Package not deliver yet

I place a order on **th jan ****, it was expected to receive on ** rd jan at Patna, flipkart showing it already reached at Patna, but they didn't deliver yet. I already mentioned two mobile number but they didn't call yet, Now it shows they will deliver on ** th Jan. Amount already almost deducted from my credit card. If I cancel the order, bank may be deduct the processing charge Rs *** and **℅ gst tax charge around Rs ****, how ever when I booked it, it's shows no cost EMI, can any one tell me if I cancel it, how much amount will be deducted from my account, Rs*** processing amount only or bank will deduct Rs **** which is showing it is paid by Flipkart at the time of purchasing. There is already alot of negative review regarding this seller. And pathetic services given by flipkart too. Definitely it will be my last purchase from flipkart.
