Sworn at by Standard bank and the worst service Ive ever had

Been sitting on hold with this bank for the past 2 days for 40 Minutes at a time with regards to an application I submitted and would be called back within 1 business day (thats a total lie from their side) I opened a prestige account with standard bank in hopes that I wouldnt have these issues as I had experienced these issues with my previous bank but based on this utterly dreadful service it seems my previous bank was the better choice. I had asked standard bank to phone me and when I get told its standard bank is calling me I simply tell them I cant hear them properly and the reply I got was "what the f*ck is going on" . Some bank you are saying that professionalism is important to you. What more lies would you like to tell us ?
