Worst service - Upgrade

Worst service ever. I have upgraded in June - Still haven't received my handset. Although they charged me for the new hand set. Today I phoned Cell C - Customer care after an hour on the phone being transferred from A - Z two consultants hung up on my call. My issue hasn't been resolved and I am still in he dark. They should either refund me or give me the new hand set. Day Light ******* and their consultants are *********** to assist.
