Disappointed Loyal customer

Two days ago I found my number “locked”. Not sure why. I couldn’t connect to the internet or make calls. I called customer care as suggested in the voice response I get when trying to make a call. Customer service had no idea how the number got locked or how to fix it. I made numerous calls trying to find someone who would help, it’s either they show no interest on solving the problem or they come up with solutions that are not practical. Like suggesting that I need to go to a branch, mind you I’m 400Km away from the nearest branch. What’s worse they have accepted that the error is on their side yet I need to travel that long to have my phone unlocked. I have 5 active contracts with Telkom and at this rate im considering cancelling all. I can’t accept such mediocre service and inconvenience. What’s worse after all this all they gonna say is “we apologise…”
