Glitching app, holding on forever

Have app**** for probably the smallest credit card, the website was full of so many glitches, filling in things then being directed back a page and forward and so on. Eventually I completed what I hope was everything, received a reference number, emailed my documents to the email address provided by them, and tried to follow up to see if it's all received because of the website glitching all over the show, and I waited for 10 mins on the line till my airtime ran out. Can someone assist immediately, because I've given my personal information to a website application form that was doing weird things, and you wait for responses from nedbank for days. Cannot hold on the line anymore than I did now. I don't have that time. If I'm opening or trying to open a credit card with the bank, they need to atleast be responsive. Can someone tell me if my information was received and what happens next if it all was received in orderly fashion!
