Order paid for no delivery

I ordered a television set on the 25th of May 2024 online. Scheduled date delivery was the 31st of May. My sister then passed away on the evening of the 30th of May and I had to go home that same night. So I called the call centre to reschedule a delivery for Monday the 3rd of June. I received a reference number acknowledging that Monday the 3rd was fine to reschedule ‪***‬. I have called the entire incredible connections lines complaining my order is not promising at all. I keep hearing that an urgent log has been done to escalate the delivery but I think as soon as they drop the call they forget all about me. For instance I've received two calls after complaining from ‪***‬ Rochester Customer Service from the 3rd of June I was told by the lady that my order would be processed as urgent. Till this day I've hear nothing. Terribly disappointed terrible customer service
