Unsatisfactory dealings with call centre agents

Got a message last night that a debicheck mandate was changed. Called the FNB call center and was shunted backward and forward to 11 agents, 3 or 4 phonecalls and 45 minutes later, no resolution in sight. Eventually figured out, without FNB's help what it was all about. Please don't try "apologies for the inconvenience caused" because it does not take away the frustration caused by dealing with consultants that seems to put you through to whomever just so they don't have to deal with the problem
