I booked a return trip; then I needed to change only the outbound trip (but not the return trip). I called TaxiCode and talked to Mujtaba Hussein asking for the change. He mentioned that changes are not possible, that they need to cancel my trip and re-book it again. I accepted, they made the change to my outbound trip and by mistake they have changed the return date (to the SAME DAY than the outbound trip) instead of keeping my original return date, as requested. As I assumed the return was not changed I did not payed attention to its date, and only checked the new outbound date. I made the payment and then I start to get calls from taxi drivers saying that they were waiting for me. I have lost the booking and the money of my return trip. They never recognised their mistake and made me pay for it.
