We had a very bad experience with travel trolley. We booked our flights last year and unable to travel on selected dates due to the passport renewal issue of my son. Our bad luck started when a customer service agent Diya from travel trolley changed our flights tickets into the voucher.......As she told us company deduct 250£ per ticket if we cancel the tickets. When we tried to booked tickets after 4 months with the same customer service agent first she refused to share the vouchers codes very rudely with a statement you have no option to booked with travel trolley again . The original price of tickets shown on british airways Website was 2790 for all travellers which we confirmed multiple time. we already paid 2472 . The travel agent diya asked for 894£ paid by my husband and she confirmed tickets are booked for all travellers. We already known we spend more then original price of tickets. After 1 hour we received a call asking for 450 £ more to confirmed the tickets . After a huge fights with most of customer services agents we realised that we are already trapped very badly and no option now to pay the rest of the money demanding by the agent. We learnt a life time lesson thanks to travel trolley and especially their customer service team for it . If u love your self and your money never used third party websites. Spend little more on official websites for buy tickets as its secure. Regards. Maha
