Just to make a sale!!!!

I was at Makro on 3/10/2015 for a upgrade and had a catalogue in my hand. I explained to the lady in store Sophy exactly what i wanted, and showed her the catalogue, the lady there Sophy explained<br> the deals to me, and we were standing infront of the phone that I wanted, I decided to take the package of R199.00 on Samsung, because she explained that I will be receiving R100.00 airtime and 200mb of data with the phone, all for R199.00, and a R1000.00 giftcard, and she confirmed that if airtime is finished that i will have to load again and the same is for the data, I was happy with that. Now I get my bill of R330.51 and I am charged for data and calls, when I phoned her, she had all kinds of excuses, I am very very unhappy and want to cancel as she mislead myself only to get a sale.<br> Today she mailed me saying \To do cancellation of upgrade it took 48 -72 hours
