Billed twice when switching

Squish01

I recently switched from Sky BB to BTBB. I got my MAC from Sky and provided this to BT.

I've just got my latest Sky bill through and they're charging me for BB. When I called up, I was told that the service was still active and being used (it's not - I checked the data flow with a traceroute). They're refusing to refund the money because they say

1. I didn't cancel the service until I called tonight (thought this was done when BT provided the MAC to them)
2. My contract says that I must give them 30 days notice to cancel

I had a look at Sky BB T&C's and it does say that I'm supposed to give one calendar months notice, but surely I shouldn't be getting billed twice for switching.

Thoughts/suggestions welcome

I've just requested my pac code from sky 2 days ago to join o2 there was no mention of also having to give 1 months notice aswell. They just said the broadband will stop once o2 take over and sky will stop charging for this from that point.

I thought 30 days notice was pretty much standard terms?
Getting your MAC is not giving notice, it's just an 'option to quit' within 30 days, after which it expires.
