Lost me as a client

Placed a order on the 27th of September 2018 for a ADSL line. Paid the requested refund by the 30th of September 2018. By the 22nd of October 2018 , after numerous calls and empty promises by telkom sales agents, i still didnt have a date or a answer as to when my my line will be installed.

I cancelled my order and went to another ISP , who installed my internet on the same day.

Now im trying to get my deposit back, and after numerous calls to accounts, not one consultant can give me a answer as to when my money will be paid back. I even got a answer as good as: " I dont know when they will do it, but when they get to it, they will do it" and " We dont know what the turn around time is"

You guys lost me as a client. Why advertise if you cant deliver?
