Bad service again

So i posted a review a last week about an opened sim card that i received and will not use and another sim fir my husband which has never been delivered, its now two months and no resolve, everytime i call they say they will escalate it and call me back and no one contacts me and yet im being billed. This is the second time posting this, they reply and say they cant get hold of me??? Im giving them another number now somlet see the excuse this time.
