Bad service i have recived from Capitec bank

I went to Capitec on Friday(23/10/2015) to open an account, all my document were checked and accepted(ID and Proof of Resident), after about 15 minutes of opening the account, i was told that my proof of resident was post dated i should come back on Monday with the previous month one. Which i did but on Monday it was a different issue, they couldn't accept my ID because it is damaged.<br> <br> What i don't understand is that on Friday my ID was accepted and copies were made. I don't know what might have changed over the weekend for branch manger to refuse to accept my ID.<br> <br> If they had issues with my ID i would have expected them to reject it the first time, not giving me the run around and later decide that my ID is not good enough.
