I got myself an Oyster Card with the intention of using it for single bus
journeys, so I went online to put some credit on it.

However, I was only given the option to put a ticket on it and then pick up
this ticket from my local tube station. I didn't understand this, so rang
the helpline. I was told that if I want to use the Oystercard for bus
journeys, I have to top it up at a tube station or at a newsagent's.

I thought the whole point of the Oystercard was so that you could put credit
on it online, in the comfort of your own home?

*confused*
