iFit Health & Fitness Inc. review: I didn't receive my payment

On the 31th of August I paid this company $189.00 and change to come by my home to assemble a treadmill I bought from Wal-Mart in Roseville, Mn. I was told someone would come by withthin 3 to 5 business days to assemble the treadmill. By the 12th of Sept no one still hadn't arrived. I asked for a refund, and was told it would take me 10 business days to get my money back on my debit card. The 26th of Sept was ten business days, it's the 28th of Sept, and I still have not been reimbursed!
