Non delivery of goods payed for.

Non delivery of goods payed for. Payed for an Inverter on 23 Jan 2023 after confirming with them on WhatsApp that they do have stock. Received message on 26 Jan 2023 that the inverter is dispatched. Received email on 30 Jan 2023 containing the Invoice. I then asked for delivery date estimate and no reply. No reply on WhatsApp or email and phone number on web site does not work. Bad service or ****? Guess time will tell.
