lack of communications

I upgraded my Vodacom account on the 17th January via Vodacom Online. The Ram vehicle was hijacked on the 19Th January and till today I haven't received any feedback from vodacom office.. I have been calling daily and nobody can give me an answer on whats the process.. I was told that its not Vodacom problem if RAM was hijacked and I would need to wait for the investigation to be completed to received new device. Now when waiting to cancel I am told its past the 14day period.. I am truly disgusted by Vodacom service and lack of communication. I regret doing upgrade
