Yhoooo ay I didn't know that Capitec is like this...they opened my account and took my money after that in order for them to bring back my money I have to send proof of payments,where will I get proof of payment from sassa?and yesterday I went to withdraw money from my capitec and it declined I don't know the reason why,I ended up doing cash send so that I'll get money...I'm tired of this bank if they need proof of payment why don't they see through my account because they see everything in our accounts...They only want to take my money...yhoo this is tiring
