Very disappointed

I have ordered a few items in the past, most of the time I have been satisfied (not overly happy btw) with the products and service. But the last order I placed really disappointed me. The delivery was scheduled for today, a Sunday, and I received confirmation sms messages before the time, as usual. This morning however, the only communication I received was that they tried to deliver but couldn't. I didn't receive any calls or text stating that the driver was outside. Previously the delivery person would knock on my door. Today nothing. I called the number I saved previously, to figure out what next, both times I was told I'll get a call back. I received an email though stating that the standard procedure is to cancel the order after two failed attempts. What the hell?? Nobody contacted me on either occassion but now it's cancelled. I had to place the order again only to find out the delivery date is 23rd December?? I don't understand how stock that is in Cape Town that should have been delivered today now suddenly will take another 2 weeks for delivery? For a company with such a large operating base, their system is terrible. The customer service seems to be getting worse, but I guess this is to be expected.
