Carlos Lopez Online wholesale Warehouse Go Deal Seek Sold me 2 cell phone and Apple Airpods and never delivered then, nor refunded my money Internet

I purchased from "Go Deal Seek" :

• 1x iPhone 8 Plus 64GB - Space Grey for $525.00 each
•  1x Note 8 Plus 64GB for $450.00 each
•  1x Apple Air Pds for $99.00 each

He had several excuse of why I hadn't received them- "The items are on their way, they were returned to sender,  he was resending, the after MONTHS he was to refund my money and didn't, he sent a bad check and then months later  reached out to ME to set up a payment plan. Instead of making payments he sent  me another check for the full amount that  also turned out to be no good. He will not respond to my requests or acknowledge his bad checks.

Shortly after I made the purchase his Facebook sale site and the Go Deal seek Site were no longer available.

I just want my money back
