Appalling service from Southgate Mall & Call center

I called Telkom to enquire about settling then canceling my contract,I was told I need to go to a store,at the store I am told I need to call it was a back and forth. If that is not enough,I am given an incorrect reference to make a payment at any retail store,after standing in a queue for long,I am told it's an incorrect reference. I go back to the store,the lady at the door was so rude,I have never been disrespected like that in my entire life,ultimately she gives me the account number and tells me to do an EFT then leaves me like that. I call for the manager,the employee refuses to apologize for her behavior right in front of the manager, and she does nothing about it. She gives me her email address that she will attend to my case,so until today she has not even responded to any email I sent! I asked for an email address to send complaints to but I'm told there is no complaints department at Telkom. What an appalling service I received from both Southgate Mall store & contact center.
