Poor customer service

On 10th June using my credit card at a filling station, it declined, used the atm also declined, went onto the money app which all of a sudden was not working,. Came directly home and phoned enquiries. They ask all these security questions but can give you absolutely no answers. The operator helping could not answer why didn't work so she kept asking me more stupid questions as to when I used the card, isn't that info in front of the screen as to all the security questions I had to ask. She needed more info from another department and made hold another 20mins where she cut my call. If she has my details why couldn't she call me back? Upon phoning enquiries again I came out to another clown who couldn't do anything at all and told me she ll have to refer me to a branch, I hope you go onto your all calls are recorded so you can not hear how people loose it over the phone but to hear how stupid and *********** your staff is for people to loose it. This is perthetic service to your clients whose been loyal and banking with you for years. You should analyze your staff properly and see who would actually be of value to you instead sitting with a bunch of dumb *****s who is of no help to people. Your standards have dropped Nedbank, and now i still sit with no answers and a account that doesn't work, what the hell do i do now if not even your enquiries can help me???? When you rock up at a branch they advise you to phone enquiries. This is disgusting from your part, what do I do now
