Wrong phone delivered.

I bought a phone for my father in Durban who needed a phone urgently as his old phone is faulty. I told my father when it is delivered I will drive down and change SIM cards for him. What was displayed on the website was. It delivered. Ok to cut out losses short when open the box to put in new SIM card. After 10 minutes of use the phone losses net work. Restarted phone several times and the same issue happens. Wasted trip to Durban. I need a manager to call me as what was displayed on the website was not delivered.
