Bad customer service

Vodacom has been the the most unsatisfying service provider. If I don't call in checking on my order they really don't bother. It's been almost two weeks since my application has been approved and my device has not been sent out to me yet which is needed very urgently. I call in daily with no satisfaction at all. I am tired of these excuses and not being taken seriously. I would really like something to be done abut this Immediately and my device to be sent to me ASAP sure to Vodacoms negligence. Which will compensate for time lost.
