TRI STAR INDUSTRIES,,.POWER AIRFRYER XL Refuses refund Internet

 I ordered the power air fryer around the 15th of Jan 2017. Accidently ordered a large one and the smaller one. When the small one was delivered, I returned it, along with a note to cancel that part of the order. Then I check the status of my return, and they turned around and shipped another one a month later. When it arrived a 2nd time, I again returned it. It was received at their warehouse on the 21st of MARCH. In the meantime, the larger one arrived, but it was defective, so I returned it. They refunded the $1 trial offer payment. In the meantime, the smaller one that was returned a 2nd time is still not showing as being returned. I told the man I was speaking to to check the tracking number and he'd see it had been received on the 2st of March. That call was made to them on the 12th of April. Then they turned around and took the final payment from my debit card on the 15th of April. Long story short, I have spoken with at least t 5 so called supervisors and each told me I'd receive my refund within 3 to 7 business days,via my paypal account. I've waited 2 more weeks and called them again and was told that paypal refused the money! Now saying they will mail me a check, but they only mail on Fridays. Today is the 7th of May 2017 and still no refund.
