MTN TRASH SERVICE FROM CALL CENTER AGENT LEIGH

Is seems like i get no joy in being your client. I went to your store in Northgate, twice to change my email address as the one you have is wrong, i was told to phone 135, a lady by the name Leigh answered, who refused to give her last name. That is beside her 'twanging' English which makes it very difficult to communicate. Who could not help but referred me back to your stores. So, where is the customer service there if I'm sent from pillar to post? Also, it will be ideal for your call agents to speak words understandably,I am disappointed in your service
