Pathetic service

I have paid my absa loan in January an dhave been requesting a paid up letter from nompumelelo for months and everytime I call I get told it will be forwarded or it will take 7 days or the waiting for the bank to generate the paid up letter it's the most pathetic service I every recieved they need to learn some people and service skill they are so unprofessional when they speak to maybe they should hire qualified people
