Cancellation of allotment from builder

Hello Everyone, I have brought one apartment in greater Noida which cost me 18 lakh.As per the scheme I have paid them 5percent at the time of booking which was paid by me on Jan 2017 and 90 percent was supposed to be paid by the bank out of 90 percent bank has only paid 85 percent .And builder has promised us that he will give possession within 9 month and if he fails to give possession than in that case he will pay us the pre EMI till the time of possession .and now neither the builder are giving us the possession nor he is reimburseing the pre EMI and yesterday the builder has sent me mail saying that I need to pay remaining 5 percent which the mail has not paid otherwise they will cancel my allotment without without any further notification and bank is saying they are not going the release the remaining 5 percent till the time of possession .I have been paying the EMI to the bank regularly. So do the builder have the right to cancel the allotment??? If builder cancel my alottment .do I still have to pay EMI to the bank ? What after cancel of alottment do the builder will return by loan amount to the bank?
