Not available in my country

I got an email with a discounted VPN. I've been curious about getting one, and I've been loyal to AVG with my anti-virus, so I figured I would try their VPN. I want to use it on my PC and Android.
So I get directed to the Play store or Galaxy store. Both say it is not available in my country.  What can I then do to get the VPN on my phone?
If i cannot, then I feel quite cheated to have been contacted with an offer I cannot use.

Hi Karstin,

We're glad to look into this & clarify.
Please let us know where you're based (geo-location) & share us the screenshot of the offer email that you've received with the sender's email address visible, error message that you got from Play store to investigate further on it.
However, upon checking your account, we see that you've already got an active subscription of AVG Secure VPN MultiDevice.
It can be used on Windows, Mac, Android & iOS. Please let us know whether the program isn't installed on your computer.
We're glad to help pointing you in the right direction for your mobile query after receiving the required info.
