Cleartrip — failure to process full refund after 7 months

I had two flight bookings for family (Sane flight outward from abu dhabi tolondon in july 2019). Used cleartrip to book ba trip. About 3 days before the trip cleartrip messaged me to say flights cancelled by airline with no alternative offered. I therefore had to rebook using etihad directly at short notice and much increased cost. Requested cleartrip to process full refunds as cancellation not my fault. Took ages but one trip refunded in full - the other trip had a refund less aed1020 (Deduction described as an airline fee). Clearly not logical as ba cancelled the flight. Went backwards and forwards every couple weeks with cleartrip who ensured me they were taking it up with ba. After chasing many times i was advised that ba refused the fee refund and nothing they could do (Clearly an issue between cleartrip and ba as the other trip refund was fine). Ba wong deal with me directly as the trip was made with cleartrip but did confirm they don’t charge fees if they cancel the flight! I can only assume cleartrip are sat on these monies but they won’t respond now
