Unprofessional Agents

Since Monday 18 September i tried to log a call me back on the vodacom insurance line, I also called the number without any luck, so I've send them a email & the agent send me a form & he/she said about the insurance policy & i mailed back that i don't have a slip as it was a gift. My sister took out a contract, but kept the watch & sim card & gave me the phone but i wanted to know what can I do as it was a gift & i really would like to insure my phone but the Tobi line is a **** and also the phone lines of Vodacom. really unprofessional agents
