Hi Lyndacmorgan,
Welcome to the Community Forums - thank you for taking the time to post here.
I'm very sorry for our delayed response and to hear there's been a billing issue with one of your former mobile accounts. It's really disappointing to hear that you haven't been able to get help with this so far.
We are keen to get to the bottom of this for you. I've popped you over a PM so I can take some further accounts details and take a look from there.
Thanks,
Beth
