Telkom is losing valuable clients

Settled my account in full as was confirmed by the first Telkom consultant. She then transferred me to the Retention Department. I stayed on the line for 20min with no one responding to my call as I wanted cancel my account. Using up and simply wasted my airtime and my time. I hope that Telkom loses clients to a point where they have to close their poor functioning business. I will never ever support this useless business again.
