Terrible communication and service

We placed an order for HP toner on 02/08/2021 at 16:31, stock was confirmed at 16:34 and we processed payment (FNB to FNB) at 16:58 and forwarded proof of payment at 17:20. I followed up on 04/08/2021 at 11:10 as the status of the order on the system was still not reflecting as paid, and received a reply at 12:08 that account are currently assigning funds to orders (Note that payment reflected in the account just after business hours on the 2nd, nothing was done on the 3rd or the morning of the 4th). The next communication received on 11/08/2021 at 10:42 is all of a sudden a problem with stock on one of the cartridges. Reasons were requested at 11:55 as well as a demand for all items to be delivered by COB on Thursday. At 16:01 we were informed that they cant do it (no explanation to questions asked). At 17:50 we approved part delivery and again requested information on how this happened. We received a reply on 12/08/2021 at 09:23 stating that available stock will be shipped and the back order stock will be shipped once received, still no answer to our questions. It rep****, again requesting reasons, at 10:05. Is now 13:00 on 16/08/2021, no toner, no reply to my emaiI and no clarity on what's going on.
