False advertising/ did not understand special

19Th May around 10am in the morning walked into Mall of the North Jet saw your special of Donatella denim R99.00 each if you buy 2. Went to pay for the 2 denims, was not price as per special running( jeans were marked Donatello and priced at R140.00 each as per tags attached). Clerk called supervisor and told me I would not get the price even though I had 2 Donatello denim pants, it was too much for them to take off the price R80 in total to get the special of R99 ea and i took the wrong denim --- both denims was right under sign and again had a Donatello tag and price on denim- Donatello denim is higher than they could shave off price. Why on earth do you have sign up saying 2 Donatello Denim up on entire rack with no small print to say otherwise or have people working for you that do not understand the special currently running.I clearly took my business elsewhere a R2000 cash at another retailer you lost.
