False advertising

Three weeks ago, my impulsive buying nature got the better of me at Checkers New Market in Alberton. I was attracted by a bright colored so-called "shelf talker" to the pesticide shelf. It was phrased as follows, "Raid assorted 2x300ml cans for R70.00 and R46,99 each" and no exclusions . I decided to take 2 cans and the price at the tills became 2 x R46,99 instead. I alerted their Customer service desk and I was told that there were exclusions that were clearly not on the their bright colored shelf talker. I day later, someone from the store called me to lecture me about the correct way of looking at their shelf layout devoid of what their shelf talker reflected. I fail to understand as to why they didn't use the word "selected Raid cans" instead or maybe display or group separately the Raid pesticide cans on such promotion to a different location in the store. To me, this looks like an in-store false advertising which created an unnecessary inconvenience.
