Illogical and pathetic service

Went to Absa bank twice to change my surname on my account, to my surname as it appears in my ID smartcard. The first time I was told to bring my divorce decree and a bill with my ****en surname reflecting on it. I went the second time with this information and was told that they cannot accept my Woolworths or Edgars statement, which they did not mention in the first place. So now I don't have any other accounts so I cannot change my surname on my bank account to that of my ID. Absolutely pathetic
