did not get assistance

on the 06/10/2015 I went to the Telkom walk in centre in Kolonnade Mall in Montana. I wanted to enquire about my contract when it is coming to an end or if I can upgrade. I spoke to the lady the she said she is Dimakatso witch am not sure if she gave me the correct name as she refuse to provide me with her surname and she confirm her assistance Manage is Solomon who was out of the office by the time. I asked her when is my contract ending instead of giving me the answer she refer me back to the call centre and giving me this bad attitude to my surprise why are you having walk in centre hence we can not get help from them as they are referring back to the call centre? The lady went on by saying if I need help I need to call the call centre I mean what is the purpose of the walk in centre. I drove all the way from Pretoria town to your walk in centre in believe that I will get help but no I fooled my self and wasted my petrol. what kind of service one should get?
