"cancelled my 13 weeks scan without telling why"

i have waited 13 weeks for a ultrasound scan to be done but they text only a day before the appointment says (Your appointment tomorrow at Bolton One has been cancelled. Please ring the appointments team at Royal Bolton Hospital urgently to confirm your new appointment date and time on 01204 390400 (option 1). Thanks) . very disappointed i called them to ask why they cancelled it the girl on the phone said don’t know!!!😕 i had to change change this hospital to north manchester hospital coz if they play bad with people minds in the first appointment definitely more to come afterwards , never recommend this hospital to anyone.
