CUSTOMERS HAVE THE RIGHT TO RETURN HANDSETS THAT ARE NOT TO THEIR LIKING

I have had a very abrasive experience with staff at the Cell C branch in Stanger. I had mistakenly taken an incorrect phone because i had a million and 1 things on my mind, got home opened the package and it was not the Samsung i thought i had taken. Long story short, went back to the store only to be assisted by rude people, manager included.. i understand my rights as a consumer who is paying a contract for a phone i don't want. Yes the package has been opened. The phone has not been used can go for the necessary testing to ensure it hasn't been replaced or whatever it is that can be done to phones nowadays. I want to return the phone for the phone i wanted, i am the one paying for the contract, i made a mistake, i did not go back with a broken phone or a ****** phone and furthermore salesman and managers need to speak to customers with respect, not all customers are rude and unpleasant. the staff Stanger Cell C branch need to re-visit their communication s****s when it comes to assisting customers
