Disgusting customer treatment

I am very disgusted at the service that vodacom insurance provides,I first visited a vodacom shop at Randburg square to claim for my lost device but couldn't be assisted,I was told by two ladies who work there that they dont know the email address for claims because vodacom has changed their head office,They told me to search the email address myself online.I then took it upon myself to use the online service for claims but Im still sitting with no Response and its been days. What must one do to receive the ideal customer care cause Im in need of a device and this is really annoying????
