Service Nightmare

Standard bank has been sending request to deduct my account on the 26th of every month and the date that we agreed upon was the 27th of every month which then returned unpaid. I contacted the call centre and I spoke to Dineo Ramesia and she promised that my request will be investigated. days went by without any feedback. I called them ans spoke to Sergel Prince who didn't even have a clue on how to assist me. he promised that Kevin Ponen will contact me two months later im still waiting for his call. I then called and spoke to Tebogo Ramesia and he requested me to forward my bankstatement which I did and ptromised that I will be refunded my bank charges. till today I haven't received any call from any one from standard bank but from their marketers wanting me to take their products which I doubt I will. I don't see a reason why they have a customer service department since it not working and the service that I have received from them is so shocking. I wonder why standard bank still exist since their administration is failing them so much.
