Operating problem and forgetting calibration cap with Hayward Redox probe.

Customer:
Hello, I purchased a Redox redbox probe compatible with Hayward Aquarite Flo Advance 22 on 11/05/2022 and it stopped working today. I have tried all the troubleshooting steps mentioned on your website to check if it's functioning.
Okay, thank you. In case you need my email: email@email.com
In my last order, you forgot to include one calibration cap. I only received one instead of two.

Technical Advisor:
Hello, I will send you an email tonight to confirm the replacement. I see your name.
We will add that for you.
