No Communication

I recently app**** for a Standard Bank credit card, i spent a hour on a call with a consultant (Banele Simelane) at the end of the call i was approved and sent him the necessary documentation, 6 days later i sent him a email enquiring why i havent received any response from Standard bank which he failed to reply to again, i then emailed 2 days later to follow up again, he responded the same day saying that the application failed the verification process, i responded to his email asking why it failed, why he never got back to me and also asked him to CC a supervisor or manager so that i could get information as to why it failed 7 days later and im still yet to receive a response or a call

3 years back i also app**** for a Saving accounts online which i also never got any feedback on

Please advise what is happening and why the consultant hasnt gotten back to me

Regards
