I did put in a support ticket and was told they will send me the part in my next order. This is the second time they did this to me. I am not going to order anything else so I will use the kf4 for spare parts for my other 1.
give it one more try and tell them you do not foresee placing an order atm but feel you are entitled to receive your missing parts asap
it was their mistake after all ...........
