    Incorrect description

    I recently ordered a brake kit for my trailer I went off what there description says.. I didnt read the contents where it stated the drums are for 12 k not 15k.. I called but they were wanting an additional $1500 i understand some of it is my fault and the drums are more money it’s understandable but they take no responsibility for anything.. so I would have to pay shipping for sending back incorrect drums and shipping to get correct drum.. they should make a note or something on they way there descriptions read.
