Hi there! Sorry to hear of your experience, and I'm more than willing to help you clear some of it up!
1. When you originally purchased the phone, there was a promo code for a $20 account credit, but unfortunately, you never applied the promo code upon your purchase. And we can't add it retroactively at this point in time. Since then, we haven't received any further payments other than the initial purchase.
In order for our one year manufacturer warranty to be active, the subscription itself would also have to be active within that time period. As your account is currently expired for a non-payment, we cannot assist with a warranty.
You can certainly try some troubleshooting steps, such as an external hard reset, however, if any further steps need to be taken to replace the phone, we would only be assist with an active subscription.
