Extremely Bad Service

I did an upgrade by calling the telkoms customer services. First lady i spoke to said everything was fine and she had ordered the phone for me. When i called to check the status of the order i was told nothing was done. The guy I spoke to when i called for the second time he assisted me and did place an order - i got an sms notification of the reference number. When i finally got the device it had software problems - no camera installed on the iPhone 7Plus 128Gig. I then called again to tell them about my problem where i spoke to the lady named Lihlithemba, she told me i needed to book in the cellphone for the Technicians to look into it. I refused because its a brand new phone and i cannot accept a phone with defects. I have since been struggling to be helped in terms of the cellphone being collected back to Telkom Mobile so i can get proper one. It is frustrating and time consuming to call the customer care everyday and still nothing gets done. I haven't been using the cellphone ever since and Telkom doesn't want to come get it! Kindly assist please.
