Bad total experience with tree purchase here. Was sold dead tree with minimal recourse.
Our family dog died early spring and we wanted to plant a tree in our yard for him. Trees were dormant but we were assured it would thrive in warmth and it was guaranteed if not. Purchased everything more they recommend, special soil, constant watering system and more. Dug a hole in the way advised and planted, watered and cared for same. Tree never budded through spring. Spoke to them about it and they asked us to give it more time.
Gave it another month, nothing. Called back and they said send us a photo. Did that too. Had to call a week later bc never heard back.
Told us we would need to go through the company that makes the watering system we purchased WITH the tree. Contacted THEM ourselves and was told we can only get another tree from the same place. No money back on tree or any of the other stuff purchased. Dug tree up and pulled it into the woods w/ my tractor. Got a tree elsewhere for the dog at that time. Called some time later to use credit and confirm it was current. A woman told me I was all set to come in and use the credit on another tree and all were on sale for half price. Came down the next day and picked out a tree. Was told no credit on file and nothing they could do.
I explained having spoken to someone just the day before but it didn t seem to matter. I protested and she called someone who said I would have to now return the first dead tree. They were closing in an hour so, I then had to rush home and pull the dead tree back out of the woods, get it in my truck by myself and drive it back there before they closed. Only then was I able to redeem the credit and I was charged the full price for the new tree that was on sale for half price to anyone else. Was told that is their policy on credits.
