Outdated systems ,embarassing indeed

I went into Nedbank Balfour branch to open a savings account on Saturday.The consultant told me if I want to deposit more than R10000 into the account I am.not allowed to open a savings account.It has to be a cheque account.She also said since I was a foreign national using a passport with permit ,they could not help me open the account instantly ,they needed to send my documents for verification .I left all documents needed to open the account.Monday 15:45 ,got a call from same consultant saying my request to open the account with Nedbank had been declined saying my permit was not issued by Department of Honde Affairs.Strange indeed ,I offered to send all the correspondence I had with VFS,starting from the time I booked the appointment for submission of my application,email with the outcome and email for collection ,she refused with her email address also saying they we closing and I have to come to the branch.My question is if my permit is **** ,then VFS permit application centre is dubious as well and Dha is not credible.Or someone did not do their job ,just assumed since I am.foreign national ,my permit is **** because I was using a new passport that I had the new permit put in.I am sure the Nedbank systems are outdated that they have to do a thumb suck in their verifications.It's so embarrassing indeed
