First & second bills are both for the same period and charged the same

[LaurenO]

Looking for some help as I am finding it hard to find a customer service phone number.  I contract start date was 4th September and I received the notification that i would be billed 14 days later and that my next bill would be pro rata - absolutely no issues with that.  So my first bill was charged mid September for the full monthly amount.  I have now received another bill being charged on 19th October but the period is for 6th Sept - 5th October, exactly the same period as my last bill.  So essentially I am being charged twice for the same period ? or am I misunderstanding something.
