Debit order over charged, incorrect date. Home loans

I called in multiple times to verify if my debit order was active. Useless call center. Today I got debited an incorrect amount and was passed my debit order date. I would never ask to be debited on the 3rd. Four (4) different call center consultants and they all said they don't see any outstanding amounts and all is up-to-date.

Why do we have a call center to assist? To me laziness is a huge problem and no one cares. I'm tired of going through the call center as I've been calling calling since the 28th to make sure that all is in order.

I'm being over debited for that matter. I don't know how to hold accountable as all call center consultants don't give a darn.
