Re. your refund - this would have been purely goodwill. Oyster has
never been able to charge in the way that you think it should.

I hope this was made clear to you when the refund was agreed.


"never been able"

Cite please.

Previous explanations of Oyster capping here and elsewhere showed this
working as would be expected, with no cases where using two PAYG Oyster
cards would give a lower cost.

So how can we explain the OP's problem, where it would have been cheaper
to charge for a Z1-4 plus a single journey 4-5?

This seems likely to be a general issue, if that extra £1.40 journey
causes the cap to rise from £10.80 to £16.00
