Clarity on my mobile bill please

[#1]

Why when I started my mobile on 14th and paid a month upfront is my next payment due on the 27th?

I could understand it if it was from the same DD or even bank account as my home phone or internet account but as it's from a totally separate account and seperate DD I don't see the relationship between the 2.

Hi @Mayfly, 

Thanks for getting in contact with us about your bill. 

This bill would have been produced automatically and should be for £0.00, as your first Direct Debit is actually 6 weeks from the SIM activating. 

If you'd like me to check all this for you, on your account, feel free to send me a Private Message.
