Delivery dates are not honoured

Stargas is in some way the South African distributor of ALFA FIORNI, an Italian Pizza oven and peripheral company, who in turn offers there product for sale in South Africa. After purchasing items from the online platform of ALFA FIORNI, who did not indicate that items are out of stock, I did not get my items delivered as per the company's terms and conditions indicated. I followed up with a very helpful Whatsapp link provided on the ALFA website, and the owner explained that some items were not available, nevertheless, the marketing person will contact us for delivery dates. This is where STARGAS comes into action. The salesman called us and informed us that some items are on backorder but delivery should happen within that week that we spoke. Another 2 weeks passed and again I had to chase the delivery of ordered items through ALFA FIORNI. For the second time the same sales person called me immediately after, explaining that the items did not yet arrive and still could not be dispatched, but the anticipated date is now Friday, November 17. This date also now passed without delivery and hence the reason for this bad review. In each of my conversations with the salesman I was quite clear to say that I am flexible to receive the items, but due to the extreme costs involved, I just wanted surety and clarity of the exact delivery date instead of having to start questioning and second-guessing my own choosing to purchase these items online.
