Microsoft 365 Copilot Bought on Play Store not Received

I bought MS 365 Copilot from Play Store. When Google Play Store couldn't deducted my sub from my primary payment method (from Country A), they used my backup payment method (from Country B) - which wasn't a problem for me. The money was deducted and still appears on my play store subs. However, my MS Account does not show any MS 365 Copilot subscription, which effectively means that I can't use the service. 
What's frustrating is I'm now being tossed around the two companies. Play Store says I should contact MS Team (devs of MS 365 Copilot) while MS Team doesn't reply to my emails sent to the emails on their Play Store app page. I tried regional phone numbers and I'm referred back to MS Team. I'm now left with no money and without the service that I've paid for. Anyone who knows how I can resolve this. I tried Play Store refund and they said my purchase does not qualify for a refund citing their policy.

Additional Context:

1. My account is registered in Country A, together with my primary payment method. My backup payment method is from Country B).
2. I signed up for the trial version intending to buy. So, it's me not anyone else who purchased on my behalf.
3. The transaction appears on my Google Play account and I've no problem with that.
4. The challenge is: My money is gone, I’ve no access to the service for which the money was deducted.
5. What frustrates more is all emails from Google Play team were sent through no-reply emails. So, effectively, I can't contact them back to clarify the challenge I'm facing.
6. On the other hand, Microsoft team is unreachable. I sent several emails and none was replied.  Worse, one of the emails on their Play Sore page returns: email does not exist...
7. Until now, the product isn't on my MS account but appears on my Google Play account.
8. The reason I'd tried the refund route was to get the money back so I can purchase an alternative service or retry with my primary payment method. It wasn't because I thought someone had purchased by mistake.
