BAD SERVICE AND NO SPARES AT EMPISAL

I HAVE BEEN TRYING TO GET A SPARE FOR MY NEW EMPISAL OVERLOCKER, AND NO WHERE CAN I FIND A FREE ARM. HOW CAN YOU NOT HAVE SPARES OF A USELESS PIECE OF PLASTIC THAT IS PART OF THE OVERLOCKER? NO ONE EVER GETS BACK AND THEY NEVER HAVE STOCK, EVEN IF YOU WANT TO ORDER MORE THAN ONE. RIDICULOUS!!!!!!!
