Poor order accuracy

On 29 August I placed order ********** 4, instead of receiving a pack of 5 replacement filters for a reversed osmosis system I received 4 filters. I decided that it would be easier merely to go and purchase the missing filter from a competitor. On 29 August I placed order ********** 7, I received the Big Blue cartridge housing, however received 5 x 10 inch sediment filters not 3 x 20" filters for said housing, now scheduled for upliftment. On 31 August I placed order ********** 4, the tent was indicated as 'in stock' with the ground sheet having to be ordered in from the relevant vendor. To expedite the delivery I cancelled the ground sheet, yet the order remained in a 'stock allocated' status with no movement. I subsequently cancelled the remaining item (tent) and ordered a replacement item from the Cape Town warehouse.

Call center acts as gate keeper, so access to management is restricted.
