Cleartrip — rude behavior and I am not able to cancel a flight

I am trying to contact cleartrip via their call center, since yesterday
either they put the call on hold for 15 min or promising a call back which did not happen. ( they told me to contact shanghai airline)
I am want to cancel a flight will take a place by 12/12/2019
all i want is to know if it going to be refunded or not or fully or partially,
They are not professional at all they hanged the call up twice.

I contacted shanghai airlines (8/12/2019) (4:30pm) UAE timings on
+[protected]they asked to contact clear trip)
and the agent shouted at me and told me to stop talking.
it was the most rudest behavior ever and he refused to let me to speak to a manager,
i called again asking for any answers or even the complaint if it was reflected he hanged up the call!
i want to complaint against them and an answer for my simple inquiry before the flight date
