I booked two train tickets from Paris to Brussels. Trainline did not send email confirmation, sms confirmation of tickets. Plus, if you can able to reach their customer service, they can not find your information too. If you want to file a complaint they respond in four days. Here comes the good part they easily accept your 200 euros and refuse to refund. Instead you have to spend another extra 200 to get new tickets from elsewhere. It is such a scam that, this day and age they really think they can get away with it. Overall awful service never, ever use when you are traveling. Avoid it all costs.
