Unhappy customer

I'm really upset with the service I received from the cell c call center agents regarding an upgrade I called the agent on the 10th of this month am according to her the upgrade was successful I called in on the 14th an was told that the phone will be delivered before the 17th called again I'm the 16th an was told that there's no stock of the phone I was told to go in to a cell c store as the consultant over the phone could not assist. I go to the store spoke to a consultant who called the agents an was told to do a reversal which was done an was told to come the next day went in on Friday but the reversal was still pending I called an agent again an was told that it takes 3 days which wasn't told to me the first time I called long story short the level of service I received from the cell c call center agents was pathetic I was transferred from here to there I literally spoke to 7 agents an got all different stories I was on the phone with them as well today for 18 min just to be told that they can't do the reversal till monday an please don'tget anyone to call me back so tired of speaking to agents who knows nothing
