Standard bank offer ZERO assistance

Card transaction declines, I re-insert my card and then it was successful but my account was then debited twice. Srandard bank makes it impossible to report this matter! Filled in online form to report it, no response. I called them three times, each time the call is about 20min and their lines are terrible! The line got cut twice and no one bothers to return my call and on the third time, some dumbass called clifford refuses to open up a case for my query or just to investigate the matter. Its the worst service I have received this year. I want you to pay back my money and then i want to cancel my account. I will open an account with a bank that has a basic concept of customer service.
