Lose average spend of R7500pm for refund issue

I spend over R7000pm on my profile. One of my lines was due for an upgrade. Went in store 4pm 11/02/15. Explained my requirements i.e. entry level voice contract with minimized subscription and NO additional costs. Samsung A5 suggested and I paid R150 connection fee. Got home to find a Nano sim is required.Phone untouched! Discovered that night that better alternatives exist. Went in store to return the phone. Consultant agreed and said it will take 7 days to reverse. In an attempt to get me to keep the phone, he offered me free headphones and a cover for the device. I refused. <br> As a result, he seeked approval from his manager to cancel (Allister).<br> After some time, Allister walked out of the back office and approached me. His first words...\What do you want me to do with a 2nd hand phone?"in a condescending tone. I proceeded to explain the situation but it seemed to have fallen on deaf ears. He said that he will not refund the device and I should have read what I signed. He then proceeded to sit on the chair in front of me and look away...It is difficult not to feel cheated and somewhat degraded. I want a refund and I believe I deserve an apology. """
