Waiting over an HOUR for someone to help me

I phoned Telkom this morning, wanting to add another email address to our account. I ended up hanging on the line for over an hour when someone answered and passed me onto another person who then passed me onto another person again. I then got CUT OFF! I am furious at the length of time I had to sit and wait on the phone. We only have the one landline at work and holding up the line to speak to someone at Telkom and not even achieving what I wanted is even more infuriating! When someone has the time to help me, give me call on *** and I WILL NOT be phoning again to only waste my time!
