"please have more phone lines at breast clinic"

please would someone in authority try to ring breast clinic reception on 622631 to see how hard it is to speak to a member of staff. I have tried over 7 days now at various times of the day both direct dialling & through the switchboard. it is either engaged or I get the ring tone for exactly 6.15 minutes before the phone is cut off only to try to get through again. the call centre on 604444 cant change appointments apparently so they advise to ring the clinic directly but it is impossible to actually speak to anyone there. it would be helpful if the 604444 call centre staff could change my appointment or if I could do it on line like the 'choose & book' system allows. it is extremely stressful enough to be having tests & this situation just adds to that stress. please review this thanks
