Told to cancel contract instead of help

Upgraded to a New Cellphone via The Grove Mall Vodashop, I told the consultant clearly that I need an Iphone as I am using iphone products, but she gave me Samsung S6 I gave her my iphone for her to do a SIM swop, and she brought the phone which I did not realise is Samsung S6, It was only at home when my SIM on the iphone was deactivated and I had to activate my new phone that my husband brought it to my attention that its a SAMSUNG, and not iphone, as he was inserting the SIM for me.<br> I thought okay I will have to return it, but due to time constraints I had to leave PTA with stock for my shop the following day, so I decided I will go in the store in Phalaborwa to have it changed for me but I have learned there is no store to take it. Called the Grove branch, Soreta the manager told me direct they won't take that phone back because I signed for it regardless of what I was explaining to her<br> I asked her what I should do since I was not happy she said I can call *** to cancel the contract. I tried to tell her that I have no problem with the contract but just the device, but she was very adamant and not interested, She said if I send it to them they will send it back to me,<br>
