Account querry

I Previously was with Nashua Mobile. I had no problems with them over the years i was with them.<br> I have been told there is no insurance on my phone. But yet i am still being billed for the insurance.<br> Customer service is not willing to assist all i get told is that they have exculated the problem. Two months later i am still paying for the insurance. Have even gone into the branch and no one is willing to assist me.<br>
