Pathetic Client Service

I app**** for a cellohone online on 8th October, the application was approved, the installment was deducted off my account on 110th October and I was promised the delivery by the 16th, I called on 17th and was advised that the cellphone was already with the courier company. I called again on 19th to get a tracking number and was advised that the cellphone had not yet left the back office. I have made numerous calls and held on for a while and still I have been given no positive feedback, I have been advised that I will be called by team leaders at the sales dept but still nothing, I was promised that a tracking number will be provided to me via email and I have received nothing. Why was I misinformed, I am calling and enquiring as I will be out of the province for 3 weeks and I need the cell and sim urgently. I had paid off my contract with Cell C to join Telkom and I am disgusted with the service that I have received. I do not feel valued as a client and my service experience has been fraustrating and pathetic.... why were you so quick to take my money and not provide a service to me ??? I want answers !!!!
