Waste of my time

I was emailed a special for the purchase of Smashbox Products stating if you purchase over R500 you would get a free legendary lipduo. I placed my order online and no free gift was added to my bag so I call the online call centre to query this. I was promptly put on hold for over 15 minutes during which time the consultant comes back to me to advise me that the playstation special is over. During the time I was on hold there was no feedback or update given just dead silence, no I'm still busy checking. So I explained to her again that red square only sells makeup products and I am querying the smashbox special. She advises she will go check again and places me on hold for an additional 5 minutes during which time I hang up having been on hold for over 20 minutes in total. I find this kind of customer service completely unacceptable and if edgars is advertising a special sent to online customers it should be available online otherwise this is false advertising. Furthermore I should not have to waste my time and money with an *********** helpdesk agent who after having seen the special stating valid until the 15 December 2015 still needs to go and query it!!
