Bad service

I am trying to change my surname to my marital surname so that I get payment from my maternity benefit from the department of labour being the only one employed in my family and having a 4 WEEK SICKLY baby capitec wants me to wait for a new ID book which will take 30 days or longer considering government departments. I have no money, I have the marital certificate, my previous ID, my current temporary ID but they insist in making life difficult for me in getting funds, my 4 week old son needs to go for his check up soon cause he had some complications at birth I have no funds I can access cause Capitec refuses to help me. The worst part was getting a consultant today call with the last 20 I had in my account to try solve the matter be so insentive towards my situation. I HOPE THE MOTHERS AND FATHER'S THAT HAVE SHARES OR OWN CAPITEC WILL BE HAPPY OF MY CHILD DIES
