Poor customer service, poor communication.

I logged a complaint about Cell C's incompetence on the 17th of this month. Today is the 26th, there have been no communication from Cell C regarding my request to port from them. They promised me, that they would liaise with Vodacom and revert back me, no communication this whole week. I've been in their store at Westgate branch a few times already trying to sort this out, it is a total waste of time to go to that store, they are always unable to see anything on their system and instead of being willing to assist. They refuse to communicate with their porting department to sort out the problem internally. There is no record of any actives or notes made on their system to create an audit trail or make it easy for any person who access my record to understand what is happening.
