I wish l can give them big ZEROS, never try to purchase ticket from them their customer service is awful and never helpful, never answer your emails, l purchase tickets for myself and my elderly parents to go back home after 17 years ( as l knew our tickets was un refundable but this up going was not on my hand) but a week before of our flight in Iran we have erupting conditions in Iran making travel impossible and unsafe, bc it was protesting for women freedom andit was all over the news then it was so dangerous to travel specially after 17 years going for visit, it was not safe for us to travel l call two days before my flight to cancel and asked for refund, they keep telling me your tickets are un refundable and l have to pay and change to another date buthiw should l know which date to choose but they made me to puy deference and exchange it l did, and then on the second date l choose still in lran was more worse and l call to ask for refund this time, then l find out Turkish Airline had a timeline for those people want to cancel their trip says they can get whole refunded and the timeline was exactly during my first date of flight and Fareboom tricked me and they didn't help at all and throw me in others hand to hand. Very very bad experience with them.
