Wesbank deduct money without authorisation.

Wesbank send a message to inform me that my vehicle premium will be deducted on the 13th of December, and not on the 21st of December as per our contract. I have rep**** to them to NOT deduct on the 13th as my salary date for December stayed on the 20th, Nevertheless, Wesbank went ahead and deducted the full premium from my account last night, while my salary for December will only e paid in on the 20th. I think this is wrong, mean, unconstitutional and in breach of a signed and valid contract between us. I have NEVER skipped a payment with Wesbank and therefore there was no reason why they should deduct money from my account which was not authorised. I have sent a formal complaint to Wesbank, only to be informed that I will receive a reply in three days time. Do they have so many complaints that they can only reply in three days!!! Whoever reads this review, please spread the Word to NEVER deal with Wesbank, as they do with your banking account as they please. I am opening a case of unauthorised deduction of money from my account, and WILL fight this in court on Wesbank's account. ****** daylight *******!!! See you in court!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
