BAD Customer Service - Online order - 13 days delay

On the 18th of August, I ordered my usual trolly of groceries (what I would normally buy in-store) and although the initial experience seemed good it quickly deteriorated. It is now the 30th of August, the items that were listed in the "part delivery section" for 2-5 days have yet to be delivered, and the items that are listed for up to 10 days delay were delivered. I attempted to contact their customer service - speaking to a very unhelpful support consultant who wanted me to go through my entire order and tell him what was delivered and who received it! I explained that this is not acceptable as I simply would like to know when the rest of the items will be delivered, yet after placing me on hold for an extended period the support agent simply hung up without giving me the required information.

The value of this order is short of R6000 and I typically buy items to the value of R10 000 Monthly. it would seem to me that I should take my business elsewhere as I see no reason why they have an online shop if I need to go to a store to receive acceptable customer service
