# Proxy You may be subscribed to datacenter, ISP proxy, residential IP, or mobile IP services but want to cancel them.\ If you do not want the proxy subscription fee to be automatically charged next month according to the billing cycle, please let us know which proxy servers and Listly account you are subscribed to at [hello@listly.io](mailto:undefined) and we will promptly check and assist with the cancellation. Even if there is no usage, refunds are difficult after 24 hours have passed since the proxy subscription fee was charged.\ This is because Listly purchases and configures the proxy servers on your behalf.\ Therefore, please request subscription cancellation by email at least 24 hours before the billing cycle elapses. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
