Phone Downgraded on contract renewal

Yesterday I went in to Vodacom to renew my contract and walked away paying more with a worse phone than I had. 2 years ago I got a Samsung S4 with my contract. At the time the phone was amazing. 2 years later I get the Samsung A5. After getting home and doing a comparison [URL Removed]<br> i noticed it is a downgrade in almost every way, The A5 isn't even included in the Samsung ADH policy. I asked my son to go back and ask for an actual upgrade. When my son got told he was insane for suggesting that I get a better phone for the price I'm paying and the sale consultant walked away saying \call the manager
