Refund For EA Play Pro

I took out a subscription to EA Play Pro on the 10th of October to play Battlefield 6, I found out pretty quickly that it does not run well on my PC and I rather buy it on the PlayStation which I have now done and it runs much better. 

My issue comes from receiving a refund for the EA Play Pro subscription which I cancelled on the same day as I took it out, despite doing this it says it’ll renew in November and have still charged me £16.99, as stated on the EA website and UK consumer law as this was cancelled well within the 14 day cooling off period a full refund must be provided, have have raised number of support cases and have been told this is impossible via the support chat, considering it’s almost impossible to find the chat system and the waiting times are over 30 minutes and you can’t close the app or sleep the device, which is ludicrous btw, I feel this is the only option now. This is a disgrace and illegal, how do I get this escalated please, thank you for any help!
