Charged for cancelled subscription

I cancelled my subscription well ahead of time and still got my account debited. Tried to call customer care because all of their other platforms have a chatbot interfaces which seem to actively try to prevent you from engaging with an agent. After all the effort, I was only to be told i'm number 200 in the queue. To hold on is at a significant cost without any assurance of when really you will be attened to. One can't email to have their problem attended to. Simply put, it's really frustrating and very different from experiences with other streaming services on the same matter.
