REFUND!!!!

I ordered a Nintendo Switch Lite on Friday on flexpay using Paypal. I received an email a few hours later stating my order was cancelled. I called 8 am Saturday morning, completely hysterical crying. Being very limited on funds and using all the money I had to purchase this for my son, I was told it would take 72 business hours to reflect a refund. The rep was so nice, spoke to a supervisor, who processed my refund immediately and told me I would see it in a few hours. A few hours go by, and nothing. I called back and was told the same thing and was told to call Paypal to see if they see the pending refund. Paypal stated they had nothing. I called HSN again, and was told they see the refund was sent to the credit department but THEY ARE CLOSED on the weekends and to give it a few hours on Monday morning. Needless to say, I still do not have my money and I called back AGAIN this morning. I was told by another rep that she just processed it again and I would again see it in a few hours. That was 5 hours ago. This is beyond ridiculous.
