Hi folks, I just received in the mail today, an offer from DS Services regarding extended warranty information. At the top left corner of the letter is a logo that looks very similiar to GM's. A bold capitalized DS underlined like GM's. Before I give this company a call, does anyone know of this group? Are they legit? Here's the "warning" alert, I only have 72 hours to take "advantage" of this "exclusive" offer! If anybody else has received this letter, could you let me know what the "deal" is. Thanks. C.J.
