I bought Eurostar tickets with Trainline, all good until my train was cancelled. I received the information of the cancellation via email from Eurostar, but I had to file the procedure to change ticket or to get the refund with Trainline, since I purchased the tickets through them. This is when all the problems started: I opted to change the ticket for one of the 2 dates proposed, but the customer service was very slow in reacting, in the meanwhile trains for the selected day were getting full booked. When they answered, they proposed me a train at 5 p.m. that was totally incompatible with my time indications (i.e. train after 7 p.m., due to work necessity), even though there was still a train at 9 p.m., but since only the business class was available, they did not even offer it to me, which is totally against their conditions, which set that in case of cancellation of a train, the passenger can obtain the change of the ticket for free regardless of the class of the ticket purchased. When I asked for explanation, they took more than 14 hours to react, they did not answer to my question and than they proposed me a train leaving at 4 p.m, because in their unjustified delay, the train at 5 p.m. got full booked. UNACCEPTABLE. The request for assistance went on, and still no answer. They are forcing me to ask for the refund of the tickets (if I will ever get it), which will anyway cause me great discomfort and the loss of the other bookings related to my trip, just because of their inefficiency in answering in reasonable time. These "intermediaries" for train tickets are good until no inconvenience happens: when it does, they cannot offer you the standards nor the promptness of the customer care of the train company, plus they don't care. And the damage is double: not only I won't rely anymore on Trainline, but neither on Eurostar, which could not provide me assistance because formally I purchased the tickets from a third party, even though I purchased THEIR service and THEIR train tickets. If a disruption event happens, the passengers are left totally alone and must face enormous difficulties and costs in order to obtain protection of their travel rights. Just do not use Trainline. Unreliable customer service. And the quality of the customer service is the core of the services offered by any company.
