worse online application ever

on 31/05/2021 i completed an online application for a credit card at Nedbank.according to the sms i received i am provisionally approved and i must send through my salary advises and copy of I.D document what i did the same day.on Monday 7/06/21 i received another sms stating the same approved send documentation what i did again to *** on wednesday 9/06/21 again the sms.phone the custemer help centre and according to the consultant there is no application of mine on their system.Now the question that i am asking if i go to the application website to re-apply,it says application already in process phone *** but that nr is unavaileble.i receive sms asking for my documents but there is no application of mine.Nobody it seems in the whole Nedbank group can give me a answer to what the status of application is,or what is happening to my details that i am sending through to them or are they just selling my info to 3rd parties.This in whole is unacceptable because it is affecting my credit score just by applying.I need answers and the correct answers on all the facts stated above
