It amazes me too!

What on earth goes
wrong with your Oyster card usage that you need to make regular
refund requests?

It's usually card readers not properly recording touches, leaving me
with unresolved journeys. It has once worked in my favour - I had one
journey which wasn't recorded at all when the system missed both the
touch in and the touch out, despite the gates opening at both ends!

Is there a particular station where these errors normally occur?
