APPALLING Clicks Online & Customer Care Service

SO this has been my experience with the Clicks website and their sad excuse for a customer service team THUS FAR, I placed an order for two make up items on black Friday weekend (the 24th of November to be exact) as they had a special on their site for NYX cosmetics products, get any two items with the cheapest one free, so I ordered a foundation and a liquid liner. I was not expecting my things right away as the order was placed on a weekend... HOWEVER now they've been taking me for one hell of a ride, I had to send their customer service an email the following Wednesday as I had still not heard anything and it said my order was still processing on their website only to be met with an automated reply saying someone will get back to me in up to two working days... Pardon ? What kind of customer service takes two days to get back to someone? Two days after messaging customer service I get an email saying my product has been dispatched, ONE product, I ordered two while the special on, I don't care when it got processed, I ordered online specifically for that special and that is what I paid for, now it looks like I'm not getting both products, the foundation is the item I paid for as it costs more than the liquid eyeliner and now they want to try and only send me one item ? Plus to add to all the nonsense I've had to deal with they send me an email 4:30 on Friday afternoon saying that my order has been delayed but nothing about the situation about me only possibly receiving one item ? Needless to say when this whole thing is over I will NEVER order online with Clicks again and I will give an honest to God review to anyone who asks me about their online service and customer care. Such a shame too because the in store employees have been nothing but sweet and understanding of my frustration and I feel bad that others make them look bad.
