What's the point of hiring people if the "system" runs Truworths?

I recently placed several orders online and not only have I been waiting forever for any sort of update on them, today i wake up to messages that 2 of my orders have been cancelled, including a duvet set and a set of pillow cases. The last order i placed was for a second set of pillow cases that apparently cannot be cancelled, so now i have to go instore to collect an item i literally have no need for. What's frustrating is that the duvet set and pillow cases i ordered ARE actually in stock, the truworths system just sent a request out to a store that didn't have stock so my orders were cancelled. Now if i want to REBUY the items i have to pay more than i initially did because the black Friday sale is no longer on. The "system" at truworths seems to be all powerful as well, no one seems to be able to override it to correct errors. They cant even tell me what my next installment is because the "system" hasn't generated one yet. Additionally, what's really frustrating, is that i placed a series of 6 orders over the space of a week. Apart from the 2 orders i really wanted that were cancelled as mentioned, ive received updates on every single order (including the pillow cases i no longer need) except the order i placed a week ago. clearly its been lost to the system somehow and i guess i wont ever know when im getting the order i placed a week ago because the system just doesnt know.
