NO INVOICE SINCE DECEMBER 2020 NO RESPONSE

Not receiving amended invoice despite repeated request since December, Cannot insure product. Ordered a Lenovo laptop 19/11/20. Order delivered Postnet 27/11. Wrong laptop was an Acer. Assumed they were applying their policy to replace if ordered product not available, set up and started working. Told I could pay extra R1000 and keep the Acer, which I did. Told 1 Dec would be provided a new invoice. Still not received.
