Cleartrip — refund not given

Website:	Cleartrip

My trip id is [protected]. I booked the flights (Sri lankan air lines) on 16th june 2017 and cancelled the bookings on 20th june 2017. Still i did not get any refund. I paid indian rs. 41652 for my booking. Once i contacted the mumbai office and they said they have sent and email to sri lankan air lines and they will refund the money as soon as they get it from sri lankan air lines. But still i did not get my refund. Today when i tried to contact the mumbai office they ask to enter the last four digits of my trip id. When i entered it they say it is not valid.
