Lowes Delivery help number is disconnected?!

We ordered a package of appliances and were given a confirmation of delivery and install this Wednesday.

Today I got an email saying our delivery date has changed and in the body of the email in Green lettering, there is a pushed out date. The issue is, the top of the email says it's Wednesday as the confirmation.

The email says "Need help with your delivery? Give LOWE'S SEATTLE, WA XDT a call at (350) 283-4942

That number is NO LONGER IN SERVICE?!

WHAT?!

Then we call our local Lowes store and they see completely DIFFERENT DETAILS than my email and the woman says she cannot help me, tried giving me a number to call...well ahe accidentally merged the calls together and guess what, the number they have is also NOT FUNCTIONAL!

I'm LIVID. Nobody can help us and then you call the main store number in Smokey Pointe and it rings and rings and rings and no one picks up? A person finally did grab the call after seven tries and it was like they answered it from their pocket as the register was beeping and were like oh, hello? Then transferred the call and that was absolutely a joke because that person couldn't do anything or provide details.

What is a customer supposed to do? We spent thousands on appliances, took time off to plan for the original date now nobody knows exactly when our things might be firmly delivered, which location is handling and what actual date the appliances we bought can be installed, the above rep who answered said they saw multiple dates for each appliance but couldn't confirm?!?
