Apple

Hi everyone, I am just asking for some help for myself as im in a really difficult situation. Does anyone know of any free or under $5 apps I can use to make calls?

Ive tried so many already, but they only give at most 5 free minutes. I missed two phone bills and of course, my line was suspended, but they actually cancelled my entire account and I cant even get in to pay off my balance. Dont have another phone or friend to call with and I cant go in person with my living situation. Im in a really bad spot right now, just need anyones advice. T-Mobile's only answer was for me to call them which I cant.
