Standard Bank's call centre service and problem resolution is hopeless

If I have to hear Standard Bank's call centre music ever again I will scream!!! I've just been cut off after holding on for 30 minutes - I ran out of airtime!!! I was trying to get to their Business Banking help line ***) to resolve a problem with their pathetic web-based banking app (digital.standardbabank.co.za). I've spent several hours and hundreds of Rands worth of airtime over the last few days. And its not only Standard Bank, First National is just as bad. One gets transferred from person to person and department to department and have to be re-authenticated and retell the story over and over again. And no one offers a reference number. Standard Bank, PLEASE get more staff for your call centres, PLEASE assign ONE person to follow through on a query right to a solution, PLEASE offer to call ME BACK when you have long queues, PLEASE reply to emails, and PLEASE REMEMBER THAT WE ARE YOUR CUSTOMERS WHO PAY YOUR SALARIES!!!
