Debit date

I went to a Capitec branch to fix my account and the consultant told me I had a policy that lapsed and asked if I wanted to reinstate it to which I said yes. However, he told me that the debit will only go through after 30 days which was reasonable so I agreed to it but to my dismay, my account was debited within days and that transaction can't be disputed. Please refund me and debit on the 1st of June. Or cancel the whole thing and refund me my money.
