Sorted...

...my laptop is back to her old, beautiful self and working like a dream. What's more, I did NOT have to pay for the repair. They conceded that I'd been to them before, back when the machine was still under warranty. Interesting, they couldn't actually find a record of my previous visit on their computer.

But then I fired up my laptop - and there it was, on my old emails!

So they graciously bowed, and admitted there was 'surely some mistake' - and dismissed the bill entirely!

Thanks to them for being so understanding! Well done!
