Ted here from Shopify, thanks for reaching out to us!
I can see that you've been unable to contact our support and I'm sorry to hear this. I know this can be very frustrating to experience but I'm going to email now in regards to your billing query so I can authenticate your account and look into this with you as soon as possible.
To help our merchants receive a faster response, we’ve moved some phone conversations to online chats, email, Twitter and Facebook instead. You should be able to contact us here 24/7 or you can contact our Facebook support here anytime as well if you would prefer.
If there is anything else I can help you with, please let me know, I'm happy to help!
