KuaiLian has completely become a burden. Are there any other big fools like me who were tricked into thinking prices would go up and renewed for another year? Some friends also said they could get a refund, so I tried contacting customer service. They were completely automated, just filled in my email address, and I haven't received a reply yet. I wonder if anyone has successfully gotten a refund?

Getting back to the main point, if this route doesn't work, then let's try another. I recommend the VPN I am currently using, hoping it can help those passing by.
First, register for the server:
After completing registration, click on the top right corner to recharge. After recharging, complete the package purchase in the store next door (it's recommended to buy a one-month trial first, since the VPN is unstable now, and it might be stable later, or unstable again). Completing the package purchase is the most important part—the installation tutorial is also in the top right corner, covering Windows, Android, and Apple mainstream systems. Just follow the steps!
I chose to download Shadowrocket. After completing the download, enter your Shadowrocket account email and password, click the login button, then select any country node and click connect to use. From my current experience, it’s completely sufficient. Although there’s no data cap, it’s a bit expensive. The basic plan doesn’t support multiple devices on one account. I’ll leave a little surprise at the end of the text—something I think offers better value!
For Apple, the installation process is quite different from Android. You need a shared US Apple ID to log into the App Store and download Shadowrocket. Then, import your purchased server URL into the proxy configuration file. The shared US Apple ID is also available in the iPhone tutorial—just find it yourself.
Finally, I recommend this service: it only costs 18 yuan per month, supports five devices online simultaneously, and offers 200G of traffic, which is more than enough for normal use.
