No reply from RMA

My husband had IOD 2015 at work in which he hurt his back.. He still has the hairline fracture in his back. He went to the doctors for more than a year and at the end the dr said he is unfit to do his normal job which is a toolmaker. Due to his back problem he developed a hip problem as well which resulted in a hip replacement after which he was two months in ICU and one month's rehab. He still is not able to walk without crutches. His disability claim was declined by RMA and we send an objection in. I do not get any reply from RMA. My husband is WAJC Oosthuizen ID ********** 089085 and got injured at Master macining. The ref no at RMA is X/ **********
