Misleading advertising

Truworths misleading with their marketing I received a sms stating buying for 750 or more and get a 150 voucher Obviously with t and c apply...no in the message stated it what their t & c are

Here I made a purchase..look for items that makes up 750 obviously 150 means a lot now a days

To my surprise after items has been ringed up.. I saw no discount..i then ask the cashier and she says that the discount is only applicable on non sale items

The store manager confirms it.when asking her why it is not mention in the sms , she says they want the customers first in the stores, and then they are only informed of the T & C That's ridiculous ..to spend travelling money unnecessary..customers need to be informed up front

Misleading marketing..truworths must give me my voucher
