Disgusting service

I have previously complained about the terrible service received from the Telkom Liberty Mall branch. My upgrade was incorrectly billed. I complained about the poor service from the Branch Manager Sudir. I have had no response. I revisited the branch and was assured by another staff member , Shamoodah Pillay , that the query will be resolved. She tried calling/emailing her operations manager , Samantha Nihal, on several occasions. She promised that I will receive feedback. Unfortunately I have had no feedback from either Shamoodah Pillay or Samantha Nihal. I have tried contacting them several times, but no response to my calls or emails. This is disgusting service.
