****** and bad service

I had changed my debit date on the 14/10/2022 for for the 1st of every month as I was debited on the 25th of every month. This change was done and was informed that my next debit will be on 25th of October and following will be the 1st of November 2022. I was however debited on the 15th of October. I called and spoke Meliwe, she advised that she will Escalate to fiance. I called again and spoke to Aphiwe and he said the same thing. My call ref number is ***. Rain doesn't have a right to debit my account as and when they please, this is a breach of contract and I want the money reversed back into my account ASAP. I have plans for my money and their debit date is on the 25th. This is absolutely ridiculous and I would safely call them ******
