I will recap on the correspondence.

I said "I was in Twickenham recently, and could not find anywhere that
could top up an Oyster."

This is a simple statement. I did not say anything about running out
of credit (whether I had or not). I might well have been trying to top
up for a journey four weeks ahead. I might not even have had an
Oyster, but been doing research.

The list of places provided earlier in this thread demonstrated that
there are a lot of places in Twickenham to top up Oyster. So it would
be unlikely that there was no where available.

That you could not find anywhere would depend on which part of
Twickenham you were in, how much effort you actually made (which you
didn't specify) and what time of day it was. I guess it depends on the
assumptions you were making - readers can't read your mind and are
entitled to make their own conclusions based on the information
available; no need to take offence, just correct the assumptions if
wrong.

Re. that you couldn't find anywhere, I can offer the following advice:
Open your eyes and take a good look around you (this may require minimal
effort); if this yields poor results ask passers by.
