So I usually use WiFi calling because of poor signal at home however recently the phone has been cut off because of a dispute that ee still need to respond about and since then whenever I make a call with WiFi calling it just diverts to the ee payment system even in aeroplane mode. But any search of the forum seems adamant that ee don't block WiFi calling, seems pretty certain they do seeing as I am now left unable to make an emergency doctor's appointment because of a situation caused by ee in the first place
It sounds like the call itself is being blocked, regardless of whether it's on WiFi. You'll normally only be diverted to the payment system like that if there's a balance that needs to be paid
