Still No feedback to confirm receipt of documents to a provisionally approved Credit Card application

I thank Standard bank that your customer service agents are so friendly. It is a pity that no one holds to their word so far in providing feedback for my enquiry to merely confirm receipt of my supporting documents to the online credit card application which I have at least received a phone call to confirm that the application is provisionlly approved, just over a week ago. The same person who confirmed that I was provisionally approved requested I send supporting documents after I had already done so, to email address *** reflecting the reference code to my application on the subject line. The Same man, advise he would be sending me an email which contained the email address I should send the documents to as it sounded different than the one I sent the documents to. No email like this has been received as yet. I subsequently sent the supporting documents again, twice. I phone 3 times and 3 times an escalation was done, so I was lead to believe, and all the agents advised they would get back to me, which none have so far. All this just to confirm receipt of supporting documents. I emailed your complaints desk about this and still no one has come back to me. Surely Standard bank upholds better customer service standards and document handling than this?
