I placed an order on June 29th. On July 2nd I received an email that my items are backordered and are not expected to ship until July 29th. I reached out immediately asking for the order to be canceled as they need to be installed in a rental property and the tenant will already be moved in by then. The process of contacting customer service involved calling a number and being sent a text that you respond to. I did not receive a response until July 6th and was told they had reached out to the production company to cancel the order. Today July 8th I receive an email saying the order cannot be canceled.I reach out again and go through the same phone call to text process. It is unacceptable that an order that cannot be shipped for 27 days cannot be canceled. Within an hour I get a response saying the item so no longer backorderd but they cannot provide me with an updated ship date. This makes me incredibly un trusting of the dates I am being, and not being provided. And worried about the overall production if they are claiming parts are not available but when requesting to cancel suddenly they are available. I still lack any set ship date and am just being told they are being produced and I cannot cancel.
