After 1 Hour holding

So Yesterday I tried phoning the Telkom call center to cancel one of my lines. After selecting all of the relevant options I received the voice note that they are experiencing high call volumes and someone will be with me shortly. Needles to say after 1 hour waiting I hung up. This is utter ******** , I believe the long waiting time was because I wanted to cancel my line, and I also believe that it is a way for customers to get frustrated and hang up the line.
