My order erased!

I was ordering a large order on jet.com through my shop.com app. and it took a really long to time to scroll through and search and find the things that my family and I were needing and I had just over 100$ worth of things for our house and when I went to put in one of the discount codes offered(triple15) it deleted my entire order and I was very upset. I am also experience a hard time getting back on to earn cashback. If you could please take note and see if there is anything that can be resolved. Thank you!
