InnoTruth Queen Air Mattress with Built-in Pump

DO NOT BUY ANY INNO TRUTH PRODUCT! I bought what I thought was a good product. Went to blow it up the FIRST night of use. It would not hold air! Next day read the instructions, your supposed to blow it up several times to help it stretch out before use. So we did that, throughout the day. About 4 hrs later, my adult daughter, flips it over, wondering why it just won't hold air, finds a small hole in the middle of the air mattress. (STORY NOT OVER) So I go to return the Air Mattress to Amazon, unfortunately I had bought it 2 months earlier, so they would not take it back. I should have tested it when I got it and not waited till I needed it. So I am told I will have to get the refund directly from the manufacturer. I tried to go to their store via Amazon, no number to call. I tried to google them. Just to get directed right back to Amazon. NOW I AM OUT $43.79! Amazon has always been good about returns but this was 2 months past the delivery date, the Issue is, I can not find contact info for INNO TRUTH
