Bill is higher than contracted

[VickyUJ]

I signed up to a £7.99 contract, starting 30 Aug, but O2 have charged me £8.50 for my first bill.

I haven't used the SIM card, and have additional spend set at £0.

It can't be VAT, as that would be more than 51p.

Any ideas what the extra charge is please...? 

Also, I'm so-far finding O2's customer service to be dismal - the voice recognition doesn't recognise what I say (even Yes or No, I'm only from York, so I don't have a strong accent!), then the phone cuts off just as they say they are putting you through to someone. Do others have the same experience?

Thanks so much in advance!

First bill is usually higher as it covers the few days between when you sign up and what will become your renewal date So 51p plus £7.99
