I comfortably book the tickets for Isd-Lhr. But the moment our schedule changed and we tried to seek your app/ representatives help the real trauma began since then . You app is not responding since last two days ,your team charged 30% Cancellation charges( which is high as a crime) . We do get change of plan but this much cost is obnoxiously expensive. Moreover ,I am waiting refund and there is no contact possible through your phone line as it doesn’t accept any kind of input for a selected number like 3 etc . This was probably the worst service experience,probably won’t be looking towards you in future. Please feel free to contact. Regards
