Recieved no help or service from Vodacom

I am really unhappy with the online upgrade service from Vodacom, I upgraded online on 3 December 2017 to date I have not received my device nor did I get a phone call from Vodacom to tell what is going on when you phone the customer service you get transferred from one person to the other and nobody is willing to assist you. When I check the waybill number on ram there is no tracking for the waybill number. I cant get hold of anyone from Vodacom to assist me to get this sorted. I am a long standing client of Vodacom and have 3 contracts with them but clearly my business is not is not imported to them. MTN is much more willing to help hopefully someone will contact me from Vodacom as I have left call me backs and 4 days later no one has phoned me. Vodacom please phone me so that I can cancel all my contacts with you. I have never received such bad service in my life and would advice others not to use Vodacom.
