Worst customer service and slowest banking consultants ever

I would like to lodge a formal complaint for the poor service we perpetually get at Standard bank central city Mabopane,i have opened a savings ,business and NPO account with Standard bank ,

I have not migrated and changed my banking details to use Standard bank as my main bank.We have been on a queue for over 3 hours while they were servicing just 8 people before they let us in. I went to Capitec and queued for less than 20 minutes with a queue that was longer than the one at Standard bank. Once i got to the reception lady and queried about the slow sergice we are getting the lady told me we (customers) are slow and we dont sign properly and once customers are done being serviced at Standard bank they tend to chat with consultants,

People that are serviced at Bulk deposits they do not queue but to my surprise the very same people that are helped at Bulk deposits they also have the opportunity to join the other queue (long queue)in side while we just stand and watch people cutting the line without any consequences.I am very upset with Standard bank and their service and when i check your consultants they are all grannies and grandpas they are old and they dont even show any energy or passion for their job
