BAD SERVICE

My mother and my sister went to the Khayelitsha branch in Cape Town to change my sister's pin card because it's blocked due to too many tries.My sister is disabled she's getting the disability grant.Now they were assisted by a lady,it's a pity that she don't remember her name and that lady said she can't help them because my sister can't talk. I'm really confused because the last time they went there to get a card they were assisted although she can't talk and she has all the necessary documents to make a new card. I'm very disappointed by the service. My mother walked in the rain,they had no money to come back.
