Samsung Electronics America Unable to return a Samsung S8 phone - BORDERLINE WITH SCAM Ridgefield Park New Jersey

I bought a Samsung S8 phone for my son in April of 2017, which came with a small hole and he wanted to return it.  We obtained an RMA and proceeded  with the return of the S8 (together with other promotional products such as a Gear VR, Samsung AKG earbuds) on May 11 2017, but my son forgot to include an adapter with the return, and the S8 phone was returned to us.  Since then, we CALLED NO LESS THAN 7 TIMES , each time we were promised that we would receive a new shipping label to return the product (now with the adapter included) after 3 to 5 business days, but THIS NEVER HAPPENED.  On the seventh call, when it looked like we would finally be getting the return shipping label, we received an email from Samsung on When it looke   July 14th, indicating that the return period had expired, and that there was nothing they could do, that the phone was ours to keep.  THIS IS EXTREMELY BAD CUSTOMER SERVICE, BORDERLINE WITH SCAM.
