这是我向racknerd提出的服务请求，帮我翻译成英文：
我有一个账单一直通知我付款，我已经支付过同类的服务订单了，已经完成了一个更换IP的服务，这个服务单无法取消，一直向我发出通知。请处理一下。
Sure, here is the translation of your request into English:
I have a bill that keeps notifying me for payment. I have already paid for a similar service order and have completed an IP replacement service. This service ticket cannot be canceled and continues to send me notifications. Please address this issue.
Feel free to let me know if you need any further assistance!
