Nedbank is full of it, what a terrible bank offering no solution

I have a personal loan with Nedbank, the agreement is that they deduct on the 25th of every month when I get paid. They decided for January they will deduct on the 22nd, I call them the consultant tell me that on her side everything looks fine, what ****es me off she kept on saying everything is fine on her side. will I call using my cellphone just to complain for something that is not there who is going to pay bank charges that I have incurred. Transferred to customer service who wants to transfer again to the same people and now I have to request the team leader, are they going to replace my airtime as well. I have stopped the debit order until they pay my bank charges, my credit record is clean so I am going to stop the debit order lets take each other on. Nedbank is full of it, they are messing with a wrong person.
