No service at Tyme bank

Most worst service of any bank in South Africa. I tried to call them for three days running. The service centre answer and that is how far you get. The service staff can't help and when you ask for the supervisor of manager they let you wait until they eventually cut the call. Every time they promised that the relevant department would call me back but nobody ever calls back. I spoke to 4 persons at the service center but nobody is willing to patch you through to the manager because they, themselves are not able to help you. Don't even try. The bank's complaint escalation service also does not work either. Nowhere can one get the head office telephone number so that one can speak to somebody more senior that the service staff. This bank should go back to basics and learn what service is. I wonder what Mr Motsepe would say if he knows about this non-existant service. Johan Joubert
