iStore Centurion and iStore Sales - how to lose sales

On Monday 6 September 2021 I placed a provisional order for a 36" MB Pro M1 with 16gb, up to 1MB storage and a US English keyboard. I asked for a quote against which to pay the deposit and was told it would take two days. A week later still no quote. I called iStore service centre on Sat 11 Sept and was promised by agent named Maye that iStore Centurion will call me. No call!!!. I sent iStore sales a request for an invoice on Sunday 12 Sept 2021 and received a reference number ***9. Still nothing. All I wanted to do is place an order and pay cash immediately. Seems like iStore could not care about paying customers who have already bought a string of Macs, iPads, iPhones and Apple watches. In desperation I placed the order directly with Apple in the US this afternoon and arranged for shipping - which I will receive before end of September 2021.
