Hi samfrench91! 

I am sorry to hear this, I assure you that this is a very unusual occurrence as the usage breakdown is a true reflection of services used on the SIM, so I would very much like the opportunity to investigate this for you today.

Could you please send me a PM with your full name and full address including postcode, so I can access your account today?
