Consistently HORRIBLE Nedbank service for 3 months, getting nowhere!

First of all i want to explain the whole situation that has been going on for the last 3 months of me asking Nedbank for a small business loan. It's taken me 3 months to get nowhere with Ned Bank's consultant Sherridan Reagon Relationship Banker: Small Business Services. She works in Cavendish Square branch. After multiple visits to the branch sometimes waiting for two hours to be told a bunch of excuses such as she went to lunch, had to leave, attend meetings etc. One time it took her 3 weeks to reply to my email. Everyone in that branch makes excuses for each other and it's impossible to talk to or even make appointment with the Branch Manager who is apparently never there. So why are these people getting paid a salary when they are never at their work place nor they are giving you any helpful information, there is no communication or when they answer to your email which is very rare it's just an attempt to get rid of you. After writing multiple emails, spending hours at Nedbank Cavendish Branch and dealing with so much stress I no longer wish to bank with Nedbank. They like to take a percentage each month from my business account, for what services? I have been with Nedbank for 4 years since i opened my business and this is what I have to deal with? I have to deal with *********** excuse making and lying consultant Sherridan Reagon who seems to always forget that she spoke to me, promised to send useful information and last time I had to wait for a cash flow document for 24 days only for her to change the dates in the document. That could have been done in 3 minutes. She even gave me her personal contact number to remind her to send me a cash flow form when she goes on a 5 days leave she will be in contact with me, only for her to never answer and to tell me how she was on leave and forgot her phone and laptop at work. When she got to work she didn't have internet connection. So many times Sherridan told me that she will email me that day or the next day or when she gets home she will be in contact with me, only not to have internet or to ignore my messages. I don't even believe she did anything for us, i don't believe she even started any loan application processes for us after all these lies, excuses and ghosting how can I trust that she has done anything? We are dealing with enough stress during these times because of the pandemic and Nedbank's *********** staff has even added more stress on top of all of this. Who do I go to, who do I complain to, is there someone that would care to help? I feel hopeless and disappointed. How did these people get their job? Who hired them? I would love to receive a salary but be on the beach and sip ****tails while my colleagues say I am on a lunch or in a meeting.
