Roku Player Hd / rip off

My wife purchased a roku player for me for christmas. She wasn't certain that i'd love it, so she took comfort in the adverstised claim that roku would take the unit back, postage paid, if for any reason we wanted to return it within 30 days. We'll I had no interest in the product and contacted roku by email that I would like return instructions. They promptly responded and said they would send me a rma and postage paid label. That was the easy part. After nearly a dozen emails and phone calls, and a dispute of the charge with my credit card company they finally, after five weeks emailed a rma and return label. Now when I email them requesting when I can expect to see the credit on my credit card, they only respond back with the standard canned response of someone will get back with me, which they never do with an acceptable resolution. I feel this company is unethical and I am so glad I didn't keep the roku and ever need support.
