Bad service

My husband and I upgraded 5th January, after a few days our brand new phones had problems which they said was a software problem. They replaced the phone with a brand new devise, still did the same thing, sent in for repairs came back and the same day did the same thing. We sent it in again on request we receive a different brand as they cannot seem to sort out the problem. This Friday will be 5 weeks, still no phone!! And we have to constantly run after the store calling and finding out what is going on.....I am beyond frustrated, and do not in any way recommend cell C!! They have no ethics or customer care! So very sad as I left Vodacom to deal with this???!!!! Shocking.....
