Cancellation is taking months and still being charged

I cancelled my Vitality following our emigration in Feb 2022 and I am still being charged monthly together with renewal fee just this past month. I called them, I mailed them, I whatsapp'd, but they abuse the system and channels of communication so they can avoid cancelling at all costs. You call and hold on forever on an International line. I am disgusted that they are blatantly acting on self-interest only because cancelling means less revenue for them and they just ignore customer requests. I am in another country...I DO NOT NEED to speak to retentions departments!!!!!!!
