Lack of communication

I am soo disappointed on Makro centurion for such poor customer service. I bought a Bosch 13 place dishwasher on the 23rd March and requested delivery. I was told they will have have stock on Tuesday and delivery would be in a Thursday, which I was fine with. My issue is the lack of communication from them, all I received on the Tuesday were multiple emails with invoices stating that my purchase with Makro centurion was cancelled and then redirected to Makro Riversands. I had also paid for extended warranty on my purchase which was also cancelled. My frustration is why no one explained what was going on and when should I expect the delivery and whether my extended warranty was still valid hence now the invoice is only showing the dishwasher purchase with no extended warranty at Makro Riversands. I also tried their customer care where the lady told me she was busy with a customer and would call me back but as expected no phone call came through!
