Sub-Pat service as per usual

I upgraded my contract and I was advised that my order was processed and confirmed and to look out for the quotation via email. I didn’t receive it so I called back today and it was then sent to me and I was told that my device was in the stages of delivery and would arrive by Friday. Literally seconds after that call ended I receive a text that it is now out of stock. I called in again and the consultant I spoke to then advised I may need to wait a few weeks. This truly is terrible customer service, you cannot provide false information or set obligations which will not be met. I never would have placed the order of I knew this would be the outcome.
