Bests & Worsts Reviews from Amazon

Bought mower and battery combo from Home Depot. I wrote a previous review about one month ago about the diminished battery capacity I was experiencing (went from mowing approximately 95% of my yard to about 50% within the first month).  I was very impressed at the time that I received a call from a Ryobi representative about a week later to follow up on the review and find out more details.  They apologized for the diminished capacity and offered to send me a new charger and battery, letting me know to stop using the old charger when it arrived.  It’s been about three weeks since the call and I can now only mow about 10% of the yard before the batter dies, basically unusable.  I called today to see why I had not received the new battery/charger yet and to check on the status.  I was told there was no record of the call and no order, and transferred to warranty after I explained the issue.  Warranty told me that based on my description, the battery was still functioning fine because I could still mow 10% of the yard and could not replace the battery until it was no longer functional (even though I’ve lost 90% capacity in two months?).  Based on a several hour charge time, it would basically take a week to mow the lawn at this point 10% at a time.  Although I like the mower, again, unusable at this point two months after purchase and Ryobi now is unwilling to do anything about it even though I was told originally they were sending a new battery and charger, unprompted.  Went from being impressed to disgusted with customer service and warranty.
