Poor to No Service Delivery

I've purchased an item from Babies R Us on the 28th of November 2020 online. Have been unable to track my order number as the sites states that the order does not exist. I've emailed the customer service department twice regarding this issue, to date, no response. I've tried to call the customer service number supplier, also no answer. This is unacceptable as I can provide proof of payment and expect delivery of the item purchased.
