Stop taking my money

I've canceled my policy in June already but Miway still debit my account now I'm struggling to get my money back the service I received from the customer service center is very bad I spoke to a Joy refer me to the manager who said that she would contact me which never happened its always me phoning them. Then I spoke to a Kathleen in the refunds department also said she gonna contact me but to no avail so I am really really angry and still waiting on my money and it's not going my way never ever again.
