Hi,
I have got penally for the same issue at Wimbledon station - I was following your thread since March 2018 and glad to hear that you have succeed!
I am traveling from Wimbledon to Croydon for the first time and had missed to touch two time before proceed into tram, unknowkingly that it is a specific action needed for only Wimbledon station.
I was in UK for a period of time - and now back to my country and had to appeal via air-mail from here to defense my right.
If you don't mind, can I mention your case in my appeal, just for proving the fact that I am not the only one missing to know that at Wimbledon station there are these rules for touch in 2 times and the signed they put flat on the side of the wall are inadequate.
I have only received my response for my 1st appeal today - and of course, rejected.
Anyhow, does anyhow in the case that I lost, how I could pay the penalty from Asia country?
Thanks in advance and sorry for my English
