Hi Redvee1
I can see a payment has been made to remove the restriction, The reason for the restriction was due to the account having a low usage limit of £20, as soon as this limit is breached the bar is automatically added until a payment is made.
Looking at the account this is not the first time this has happened (3 previous times) I would suggest to prevent this re-occurring, either raising the Usage limit, or adding the anytime calls boost which will then make the chargeable calls free
Please accept my apologies for any inconvenience caused
