Expedia Don't honor best price guarantee Internet

I booked a package deal with Expedia. I later found that same exact package for less price. As per the Expedia Best Price Guarantee, I filed a claim on their website less than two hours later. As per the instructions, I attached screenshots validating and showing the lower price and details. Once I submitted the claim, I was advised that Expedia would get back to me within 48 hrs.  

After several days of not hearing from Expedia, I contacted their  customer service again. who stated they would get back to me within 24 hrs. They finally got back to me after 72 hours. I was advised that they had no record of my claim. I then called customer service and was directed to e-mail screenshots and evidence of the claim I had filed since Expedia had no records. I e-mailed Expedia screenshots, photos, e-mails and other records demonstrating that I filed a claim. Each response from Expedia was the same, that they had no record of receiiving a claim and could not proceed without the case I.D.

I tried numerous times, all in vain, to advise Expedia that their own system lost, deleted or misplaced my claim and I had no case I.D.; which was the reason I attached the other information and proof they requested. Each time, Expedia just kept denying my substantial poof because they did not have a record or claim.

Expedia did everything possible to deny my claim and evidence without justification. It is also suspect that they will get back to you within 48 hours when they know a customer can only cancel reservations without any fees if it is done within 24 hrs, how convenient. Expedia will not honor their Best Price Guarantee so if you find a lower price elsewhere, book your travel there. I wonder how many other claims have been denied under the guise that they never received a claim. It is also very suspect that the claim was filed and submitted via their own pop up window or tab rather than a claim you actually e-mail in from your own account and could easily prove it was sent to Expedia
