Multi choice

I received an sms from multi choice, they were running a promotion where you can upgrade from your compact to compact plus and you pay 460 for 2 months. Now to my surprise i was bulled 517 which is what i did not sign up for. That is false advertising why advertise 460 and charge your clients a different price. I am very unhappy about this, i also called your customer service and the guy told he's unable to help me that i should just pay the 517.
