A bill for Staples

I just got a note from the insurance company saying they are sorry but they won't pay the invoice for 25.50GBP as I'm now longer covered.

What! er what 25.50, what procedure was that for!

So I rang them and apparently the surgeon only just got around to billing for removing the staples from the surgery all those months ago.They said they would sort it out.

So the whole thing is still not settled
