Went to open the account and been returned over

i went to open an account and i was told to bring the proof of resident of which i had my bank letter that was posted to me and they said it should be a letter from the account or municipal,fair enough.When i went there i had my id,marriage certificate,drivers license which proves my previous surname and proof of resident,to my surprise that was not enough i was told that the proof of resident should have the same surname as my id and i find it so difficult to understand cos i have also produced my drivers licence and marriage certificate to show that i have changed surname.i want to open an account but i didn't get any help after the returned me home so many time,so i also dont understand if another person can open an account with landlord municipal letter why cant i be assisted whereas i brought so many proof,and i also like to know that i wont be assisted cos now i don't get a mail or post with my current surname,why did they ask for marriage certificate after all.I am very disappointed with Capitec bank and i think their are overreacting,i am working and i know all about Fica and KYC thing,before you loose more client please do something
