Poor nedbank service

App**** for a credit card and received sms stating I have been provisionally approved,after several attempts to follow up status was told need to go into branch to update my details,went in updates my details but still haven’t had any feedback,call Centre is of no use and the number I was given to verify my details you hold on for an hour or more and no one takes the call,tried the number for several days no luck,branch can’t help,call centre can’t help...who then can help...very very poor service from nedbank,my husband is an account holder there and we thinking that maybe he too needs to change his bank...very disappointed
