Nedbank, complete and utter idiots

Last month I had spoken to a consultant to arrange a debit order of R300.00 to go off my account on the last day of the month in relation to my credit cards which has not happened. Upon numerous times stating to Nedbank that they should not call my work number as we not allowed to take personal calls a consultant still phoned yesterday after I had left to which my boss had answered the call. Please do not phone my place of work in any event, rather email me as I do not like giving out my details over the phone nor do my staff and colleagues need to know my private life. Anyway the call was apparently about the credit cards not been paid but they would have been paid should your'll have followed through on your part. I dont know if yourll are *********** or just plain dumb honestly, or perphaps do not understand english. If a person tells you not to phone a number yourll should not phone especially if it can cause a person to lose a job or get a warning and in that case yourll will never see your money. Be Wise not dumb.
