Bad service

On 2019-01-31I went to elim branch to change my student achiver account as i am no longer a student and im over age and i am not working i cant afford to pay R70 monthly service fee as access account is R5.90 which i can afford. I was assisted by nancy munyai who refuse to change my account she told me that access account is expensive but according to my understanding R5.90 is cheaper compared to the 70rand that im paying now .instead of changing my account she replaced my card which she charged me which i did not agree . When i went to the bank i new what i wanted to do she should have listen to me instead of doing what she think it is right
