WORST CALL CENTER EVER

I have been with nedbank for years now and have never had a problem up until now, I have a pending debit on my account for an amount of R1686 with no indication as to what this debit order is for. I have contacted the service center and was transferred 5 times, each i spoke to someone they advised that this is the incorrect department - I have been on hold now for 1hour and 30min with no assistance from anybody. Each time I do speak to somebody new I have to explain the situation all over again like im a parrot. If this is the customer service that Nedbank provides I want absolutely nothing to do with them - I am not against changing banks.
