365 wearable plan - refund?

I have been emailing Spacetalk for 3 weeks solid trying to return an unopened loop watch. They’ve finally given some advice on how to do it after I wrote a formal complaint letter on advice from Consumer Affairs but seem to be telling me they can’t refund the 365 day plan I optimistically purchased. I haven’t activated it yet - Does anyone know if it can it be used with an Apple Watch? If not surely I should be able to be refunded given I’ve not activated it - has anyone had success in this scenario?
