Vodacom bad service!!!

Good day Im very disappointed with Vodacom. I am a valueble customer and refered one of my friends to upgrade on Black Friday after she said she wanted to go to another cellphone network due to bad customer service. She then decided to go on my suggestion and this is what happened. 1. There were no deals available and she upgraded to a normal vodacom contract. 2. A week later and she did not receive her phone. She contacted them and asked whats going on. They told her the system went offline and she must re-order. WHY does the customer have to follow up??? This is a very bad expierence and i felt I needed her to give vodacom a change and this is the type of service she got. No wonder she wants to go to another cellphone network.
