"Long waiting times for appointments"

Since first visit to gp it has been over 6months and still no closer to getting sorted.appointments for scans have months waiting time.notification of appointment none existent if I hadn't phoned I wouldn't have known about appointment and would be classed as a no show. Have seen specialist who again has requested further scan and ultrasound,phoned hospital two weeks after specialist request was made ,was told would have to wait again for a further two weeks for appointment date to be given then would have to wait yet more weeks to actually get scan etc done. Is this the way our nhs has gone it's no good telling someone they have a problem then leave them hanging,worrying and scared for months on end !
