Or is it possible to stop my plan until I pay off the current Invoice. Otherwise it will keep charging me.

How Can I cancel my subscription, with $1 of outstanding balance as the it keeps rejecting my debit card, and I am afraid the cost of subscription will keep accumulating. I started this as a free trial but cant seem to cancel it. 

I wish to close my store but I have an outstanding balance of $1 even though I was on a free trial, now it's not letting me pay through my debit card, and I am worried it will keep charging me for the next cycle.

What was the solution you found, as I am stuck in the same conundrum, Any help would be greatly appreciated.
