Worst customer service received to date!

Worst Service and Customer service received to date. I put in a request to cancel my sim only contract within 30 days. However, the next day I discovered that I did not have any internet connection, my router was down and after numerous attempts to restart I called the call center. The agent told me that my sim card was inactive. I couldn't believe it, because I listed the end date of my contract to be canceled how could they just cancel without letting me know anything. The second person I spoke to came up with the theory that the consultant thought that because there was no penalty fee, they'll just cancel the contract immediately. So, I was left with no internet to work without any prior warning, and apparently once the contract is canceled it cannot be reinstated. I will never go back to Telkom for whatever reason. Worse customer service ever!!!
