Herbal Life Order Paid but Not Delivered and Poor Customer Care

I placed an order for herbal life combo package. I received an sms stating that my order has been delivered and yet it was not delivered to me and I had not received it. I have been following-up with the call center for the past three weeks and every time I call am told to keep waiting as no response has been received in respect of my enquiry. How can I keep waiting for three weeks and I am calling everyday and nobody is assisting me. I am further told that I can't get a refund. Please stay away from herbal life as they are not proactive on following up on client queries
