To build on Western Lancer's good advice to you,
@gopi - back in December, I don't think you answered AlterEgo's question to you (linked) about your saying you bought a physical ticket but "...
missed [mislaid?] it somewhere".
Today I got witness statement in the govia Thameslink in Gatwick airport. Actually I take physical ticket in Croydon Nd after that I missed the ticket somewhere and booked online ticket in the train after that in train officer asked me to show ticket nd I showed he said you book ticket in the...

If you
did buy a physical train ticket before travel, did you pay for it with a debit / credit card?
If yes then your ticket payment transaction is evidence that you had, in fact, bought the ticket before travel.
Your payment info will only show the cost, not your [mislaid] ticket's From and To stations; however it will be possible for you to show your 2025 ticket price matched - or is very close
You need to write a reply that basically includes the following content::
- That you are sorry for what has happened
- What you have learned from the incident and will not do this again (despite the fact that you seem to have done it before so you really need to stop doing this!)
- That you are keen to settle the matter without the need for court action
- Offer to pay the outstanding fare and the railway company’s administrative costs in dealing with the matter
You'll find lots of example letters you can use in this section of the forum that you can pretty much copy
Before you post it to GTR put a draft of your reply here so people can help you get it as good as it can be as I am thinking perhaps English is not your first language so you might want help getting it as good as it can be.
You need to know that it is criminal offence to book your ticket after you have got on the train - there will be lots of signs telling you this so you need to obey them - NEVER get on a train and buy your ticket after getting on. Their ticket check systems are set up to detect people at ticket checks when they do this - which is presumably why you keep getting caught. It is what people who do not want to pay their full fare do - they only buy when they see staff checking tickets - which is what they will suspect you have been doing as result of buying your tickets on board.
