Bad and Dishonest Service

I upgraded my vodacom contract on the 08 Dec 2017. The phone battery was flat so I charge my phone when I got home and when I inserted my sim card I realised that the phone does not read the sim card. I return the phone to the vodacom shop on the 10 Dec 2017 for out of box failure. I was assisted by the same consultant to complete the out of box failure that did the upgrade with me. She checked my phone for damage as this is their procedure. She indicated no physical damage on the phone as per OBF she filled in. A few days later when I enquired I was told that there are physical damage on the sim unit of the phone and that Huawei will not replace it. The consultant then told her manager that there were damage on the phone when she saw it in the store even though on the form she indicated no damage in my presents. That is so dishonest. The manager agree to replace the sim unit at their cost. This is now suppose to make me feel happy because of a mistake that they made. Today on the 12 Jan 2018 I am still without my new contract phone but still need to pay. They give me a loan phone that is without insurances and my responsibility if anything happens to it. How am I suppose to use it and not stress. When I enquired yesterday we were told a different story again. When will the dishonesty stop. Vodacom has really gotten bad with their services. Is it only vodacom or do the other phone companies treat their customers like this to.
