Bad online system and no backup for after sales

Ordered items only and paid for it. Only received x2 out of the items. Send a mail and received ticket # ***. Thulani Lukhele rep**** that the item would have been sent out last week 17/04/26. Nothing was delivered and again sent a mail that Nothing was delivered. No response after 3 mails. Did mail again and received ticket no. #*** on 21/04/2026 and still no response. Contractors went on to another job and I'm sitting now with an incomplete paving area and can't continue with my next project.
