Dripshipper: Coffee & Tea

All of a sudden out of nowhere I’m unable to access my account to pay my invoice that had a week to get paid, I’m on day 3 and ready to pay it, but I get an email that I’m on day 6 when I paid on the 7th of May? I also paid for my subscription to your service on May 7th, and my bill says the next is due May 19th? This is a bit frustrating
