Cleartrip — trip I'd / pnr not generated

Yesterday i was trying to book tickets from hyderabad to chennai via cleartrip. I selected the flight spicejet which departs from hyderabad at 5.45 am on 14/02/2020. I applied my two gift vouchers which i got from sbi and proceeded with the payment. After the amount got deducted, the cleartrip website crashed and it said because of some issue the pnr is not generated, an executive from cleartrip will call me in next 4 hours. Still there is no call. Also it mentioned not to rebook your flight as it may lead to double charge. My 4000 gift vouchers that i had used with cleartrip are also gone along and i am having no tickets.
