Hey there @Sanjez8329 ,
Welcome to the community and thanks for your post.
We will send you a text message when you reach 50% of your Service Pass usage, and again when you have used 100%. Once you use up your full Service Pass, you will be able to buy another.
To ensure we understand correctly, are you referring that you purchased a second service pass and it is not working or when you attempted to purchase a second pass none were populating?
A quick trick is to ensure you're not connected to Wi-Fi when attempting to activate your service pass. If that doesn't work keep your Wi-Fi turned off and restart your device.
Looking forward to hearing back from you.
