Bad service home laon

Today I would like to express the worst service received from standbank home loans. On the day the bank suppose to debit my account they send me a message saying that the home loan has reversed. I then contacted the home loan department asking them to debit my account they said they can't and Ave me wrong banking details ever since the 25 Feb 2022 I have been calling them to deduct the money but they didn't they kept on changing my home loan amount every month and advise to didn't get back to me. I'm still waiting until today for someone to help me the service is very bad and I still have the money in my account but they not deducting it. The contact Centre didn't even give me a reference number for all the call I have logged
