Equipment shipped way too early

I placed an order for service to start at an address I'm moving to (renting) in late August. However, Xfinity texted me saying they were going to deliver it yesterday. Since I currently live hundreds of miles away, I contacted support, and they told me it was all fixed and squared away to be delivered in late August. But then at 9pm last night I got a call from someone trying to deliver the equipment. I contacted support again and they told me it was fixed and that there were now no scheduled deliveries. But then overnight I got a new notification saying equipment was being shipped by FedEx and would arrive Friday - still weeks in advance of when I'll be there. I called support yet again and was told that the equipment being shipped would be removed from my account, that my billing cycle wouldn't start until late August, and that I could pick up the equipment then at the local Xfinity store. However, I'm still getting a banner at the top of my account telling me "your order is on the way," and when I click on "see first bill details," it says the billing period starts "5 days from your order date or the day you activate your WiFi equipment (whichever happens first) if you're having the kit delivered." So I'm very confused at this point. I don't want to be billed for services I didn't want and can't use before late August, but it seems like it will be billing me starting in the next few days based on that. How can I get this clearly and firmly sorted out?
