I got back from a trip away to find an unexpected bill for broadband  through the letterbox. I have paid about the same each quarter for broadband for a good while now, I don’t see much variation as I rarely use my home phone, then again who does?

This bill was nearly double, why?

I think it was mostly due to setting up Skydrive to mirror my family photos and video as a backup, though this can’t explain it all, but then again my son as found Roblox. In each month I went over my usage it was costing me £5 a 5Gb block. It adds up fast.

On calling BT I found I could upgrade my package to a larger allowance and it worked out less than £1 more. The most irritating thing was they had been emailing me about my usage on my BT provided email address, an address I have never used.

So the top tip is make sure your usage notifications go to an address you actually get .
