At&t ActiveArmor

My ActiveArmor VPN is not working. It hasn’t worked since I signed up for it 6 months ago, so yesterday I finally called At&t to see what the issue is. The woman who answered the phone had no idea what I was talking about and told me. I needed to contact my internet service provider. First of all At&t is my internet service provider and and she didn’t know how a VPN works. I tried to explain it to her several times and finally, she asked any other person for help. After forty five minutes she then told me that she looked at my bill and I didn’t have that service. I told her I had paid for it for 6 months and she disagreed. I then decided to hang up instead of getting too rude.
I then decided to call back today to hopefully get some help from someone else. After explaining everything again and another 35 minutes on the phone. The man told me that there was nothing they could do. He saw where I had the service had paid for it but still there was nothing they could do at all.
It’s so crazy to me that the people representing the company do not know how they’re VPN service works.
Anyway, the issue is that I change the location on the VPN with the Smart Home app on different devices at my house and nothing changes at all. My IP still shows my home address not the city I’ve set it at. I’ve reinstalled the app three times, and I’ve reset my router twice. Am I wrong about how thier VPN works? Any suggestions? Thank you for your time!
