OK, getting a duff telecoms bill is not new, and not so bad when you have a £100 mobile bill or something.
Today I had a heart racing moment when I saw one of our many monthly BT bills was £34,000 more than usual. OK not a huge percentage, but scary.
Ran it through our checking tool that checks each line item looks correct, and it was happy - so even more fucking scary. The prospect that it could be right is not impossible if they had found something not correctly billed for a few years and caught up or something, or some charge I had missed in a briefing last month. At the end of the day, that comes out of my pocket FFS.
Thankfully, after spending some time trawling through it, I confirmed they had in fact screwed up and it was not in fact correct. They double billed thousands of lines for the same time period. The fact that the bill was 200 pages more than usual was a clue, but I had to be sure.
How does anyone manage to make mistakes like that and hope they are not noticed?!
