Got a work green weed whacker charger and battery it needs maintenance it's 3 years old don't have a receipt, I would like to exchange and pay the difference, it seems can't get it fixed anywhere price was roughly $385.00 can if live in Whitby Ontario, I also have a Canadian tire credit card so I try to support Canadian tire stores as much as possible. I did receive the weed whacker as a Father's Day gift from my daughter, any help would be greatly appreciated, am told because It's made in the states It's hard to get maintenance done,
