Bad customer service

I ordered clothes on the eve of Back Friday. As spree is my preferred online store I made sure I started my Black Friday shopping with them. This took me about 3 hours because there was quite a large selection of items. I managed or at least thought I managed to secure 3 orders before I went on to shop at other websites. As I thought I had secured quite a lot of items on spree and had reached my budget I decided to not worry with other online stores and slept at 3am. To my disappointment a few hours later I got an email from Spree to advise one of my orders was cancelled because of stock issues. For a busy event I thought maybe losing 1 item is understandable so I didn't think much of it though I was quite unhappy. Anyway got over it and thought will get the rest of the items but unfortunately was disappointed again to get another email 2 days later to inform me they can not again supply something else. Then realized this is quite a problem cause these online stores seem to be deceiving consumers making us surf their site and pay for items they dont even have. Though they credit the account its quite disappointing they seem to think its OK that they couldn't supply. I then sent an email in response to these supply issues which no one has responded to 3 days later. I then phoned the support call center. Spoke to a guy who had very limited capacity to assist me so he informed me he had to escalate my complaint. The only information he managed to give me was that one of the items was also not going to be supp****. Which was more bad news for me because I hadn't even been informed on email. He put me on hold to discuss with his supervisor who apparently informed him she will contact me on my cell number between 8 and 9am. No one has contacted me yet. I think the CPA gives the customer the right to request stock movement information from Spree that justifies why they could not supply. I would appreciated being offered alternatives of the same brand and style. The store credit or refund is no longer the same worth as the eve I bought stuff. This is breach of a sale contract. I always buy from Spree as my preferred online store for price, style, variety and delivery. Had I known my perception whole lead me to losing out I would tried other online stores or shops and saved myself the anger.
