On 5/8/18 I ordered 10 - 30oz yeti tumblers. Payment was taken from my account at that time in the amount of $154.50. I received an order confirmation and payment acceptance email the same evening. On 5/26/18 I check the website and it still said payment accepted. At that time I tried calling the phone number on their website (347-502-6139) and a recording said it was not a working number. I emailed (9:11am) them stating I had tried calling and asking for an update on my order. At 10:53am that morning I received an email saying my order had been shipped but was no tracking number. Status is still saying shipped with no tracking number. I have called several times and get a recording saying not available and I have sent several emails with no response.
