Excuse me, you're not necessarily sat in my seat . .

I have just booked a couple of train journeys with Transpennine Express—an activity I have performed for donkey’s years. Their website tells me I have seats reserved, but doesn’t provide seat numbers. This means that on busy trains there is a much greater likelihood of having to ask somebody to move, or to stand—wishing to avoid an argument. The statement that ’you have seats reserved’ is therefore somewhat disingenuous. I thought I would try out the ’live chat’ function on the website to see why things had changed—for the worse. This is as far as I got:

Pre-Ticket Data I  have  just  booked  seats  for  a  journey  next  month.  I'm  told  seats  have  been  reserved  but  have  not  been given  seat  numbers.  This  means  in  effect  that  seats  have  not  been  reserved  since  anyone  with  an  (e.g.  any time  ticket)  could  take  the  seats  available.  What's  going  on?  Have  I  got  a  reservation  or  not?
Kyle K 18:01: Good evening , thank you for using our live chat. You're speaking to Kyle on the TPE Web Support team.
Colin Challen 18:02: Hello. Have you got my message?
Kyle K 18:04: Yes, if you have selected reserved seats then the seats will be reserved. However you will not have a specific seat. You can sit in any seat that has the "reserved" ticket above.
Colin Challen 18:05: Is this a permanent change - it will still make life more difficult especially on busy trains
Kyle K 18:06: This is only the case on some journeys at certain times of the day.
Kyle K 18:10: Thank you for chatting with me today. As I have not received a reply from you for some time now, I am going to have to end the chat. If there is anything further I can help with, please do not hesitate to come back to me.

I was typing my reply when I was timed out. I’m not blaming Kyle K. here by the way. I suspect Transpennine Express have some glitch in their system which has simply prevented them from doing what they always did in the past, namely to issue reservations for actual seats. Apart from getting cheaper tickets one of the main points of booking in advance was to get a guaranteed seat. No longer it seems. I shall be interested to see what the explanation is. Having complained I am fully expecting some techno-goobledgook heading into my in-box.

Meanwhile I think I ought to start a crowdfunding exercise to help me over the distress.
