Really bad service from Vodacom Online

I would like to complain about the really bad service I got from vodacom online on the 23/10/2020. The lady that called me to assist me with the application process never asked me what my income is after tax and if I'm permanently employed. She took me through the stages and asked if I earn more than the qualify amount which I rep**** I do and then she asked my date when I get paid and I gave it to her just to be put on hold for like +- 5min and then to be informed I got rejected without any valid reason. Now I can't apply at any of there branches because it shows on there system that I'm not allowed to apply for another 60 days and what guarantee will I have that, that deal will still be available after 60 days because it looks like they are forcing people to take out the more expensive type deals so they can get a better commission on the application.
