bad client service and guarantee of makro means nothing at all

bought a ryobi blowerwith a 24 month guarantee, after 3 months it broke, it has been in repairs for two months, nobody at makro can tell us when it will be fixed, also we were told that we have to pay 50% of the price of the original purchase to get it fix. clearly the guarantee means absolutely nothing. the staff at the help desk are rude and incompodent
