Is this a new contract? If yes then you're subscription will be charged a part month + next month's payment as well as the first month's charge for the phone & Mac if you purchased those devices at the same time as the subscription.

No it's not a new subscription iv had the mac for some time and the mobile is my sim card only not for my phone.

If you are a new customer then the first two bills are always higher due to the date period they cover (longer than the usual 4 weeks) as you can read about here, halfway down the page here:

So have you checked your future bills to see what they show:

Thanks. Then that's strange. 
Has the minimum term ended for the SIM plan? Usually this lasts 12 months & after that time you'd be charged full price for the SIM plan you're on unless you downgrade/upgrade or try to get a retention's deal.
