Inconsiderate service

I have had a Funeral policy with Sanlam for past 17/18 years. Paid them without any fail and I called them last month to cancel the policy.

They confirmed that they got my request and it will be actioned however I was debited again month end of May '25 and now they want me to proof that it was debited yet I sent them the transaction of the debit.

My issue is that I do not have time to go to the bank and get a statement because I am at work Monday to Friday and I come back late.

Why can't they check on their system because I believe it will show unlike giving me the run around yet I followed process of cancellation and sent everything in time.
