Double debit

Got double debited after updating my debit date. Rain should have a system in place to prevent such things if a person changes the date after the debit for the owed month has alredy taken place(I'm in fact confused by this debit because the system advised that My next debit would be on the 1st of Feb when I made changes on the 31st of Jan 2023). Now I can't even contact the support team to log a ticket. The customer service number does not exist, *** no longer works and the support page, I was referred to by Rain's automated response after sending an email to the discontinued support email, only has FAQs and no way to log a ticket.
