Unauthorised debit order and very poor service

So Bryte life decided to debit me when I asked them to cancel this policy mainly for this reason Took cover and they never debited me,3 months later they then started debuting my account and cancelled then activated the policy,I really don’t know what they doing but if they are struggling to do one simple thing like debiting I wonder how they will settle your claim come claiming stage …Bryte life I want my money and cancel me on your systems and stop debiting me..rather not have funeral cover than to have policy with you guys ???
