Hi I purchased an HU775HW mower at Lowes. It is supposed to have a 3 year warranty according to the Lowe's website and in fact there's a sticke on the mower that shows a 3 year warranty.
When I registered the mower I got an email that shows a two year warranty. I called support and was told it had been corrected but then I got another email showing a two year warranty. How do I get the records corrected to show the 3 year warranty?
