Ridiculous service, extremely frustrated consumer

Worst experience ever!

I got convinced by the sales person that I was buying 2x Iphone 6s phones after I asked him 3 times to confirm as it said only Iphone 6 on the box. when I got home and googled it it turns out that I had indeed received Iphone 6 and not 6s.

I had to go back and then he apologized stating that he realized he was wrong afterwards but conveniently neglected to contact me to correct his mistake. He then went on to tell me that the only real difference between the phones is that they came out a year apart. Needless to say I googled it and apparently the differences in performance is not that insignificant. Now he offered to cancel the contracts as he says he cannot find IPhone 6s or 7 anymore but for double the price I am now paying he can get me an Iphone 8. Luckily I only have to make a THIRD trip back there to take in the phones. I expected this from Telkom not high priced Vodacom. I'm an extremely dissappointed consumer & i'm seriously considering rather moving my business to MTN
