Online applications

Hi There I made an online application for a credit card, last week Saturday the 20th I received an sms on tuesday the 23rd. To say my applications is in progress someone will call me shortly. I had to phone in yesterday and follow up as no one from nedbank called me, I was told application is approved it is now with verification department. I called again today was told i have to wait there is no progress and the is no way to speed up the process, due to the fact that online credit card applications take time. I asked the 2 people I spoke to escalate my applications they said unfortunately they cannot. Please assist me.
