Terrible service!!!

I made a purchase on the Momentum Multiply online shop on the 24th of July. The funds were deducted from my account and for some reason unknown to me, I never got an order number or any confirmation on the site that my order was placed. I immediately called the call center and was told that I should send a copy of my bank statement showing the funds left my account which I did. Long story short, after 5 phone calls to the call center and after being told that my purchase will be delivered to me on Tuesday (4th August), I was told on Tuesday(4th August!) that the order hasn't even been placed with the supplier as they haven't confirmed that the funds were received!! I was then told by a supervisor on Tuesday that once they confirm the funds are received I will receive my purchase by Thursday (today) latest tomorrow. Needless to say I haven't had ANY feedback whatsoever from ANYONE regarding this and I doubt I will receive my purchase any time soon. Why bother offering this service if you can't get it right?? The lack of customer service is absolutely APPALLING!
