No accountability for ******* debit order..

I had a life policy with miway Life and I canceled the policy on the 1st of July And Then boom today I get a debit order for the policy. I call them, they tell me they can see that the policy was canceled but it actually wasn't and that they will escalate the matter to management who will get back to me in within 2 working days.. It's Friday today.. So I might be getting a call on Tuesday.. Which is 4 Calender days... I Told Themmthat I reversed the debit order as I had canceled and that I hope this does not affect my credit rating as it will show up as a missed payment. Which they answer "they would have reversed my payment" which is unacceptable as I can't be guaranteed that it will be canceled at all? No one is taking responsibility for this but I'm the one who is geing held hostage by a system they designed... It's not what I signed up for.. I'm happy that I left I hope everyone reads this so they know the kind of company Myway life is....
