"Appointment or not, your guess is as good as mine"

My partner had an appointment booked at the hospital. 10 days prior to the appointment he received a call to say the appointment had been cancelled. However two days later he received a text message to remind him not to forget to attend this appointment. I spent nearly an hour to try to get clarification on this matter, not wanting to waste our time, we both work. I have at this point given up as no one at the hospital was answering calls, except reception so have been charged for call. No wonder the NHS has such a bad name , this hospital is definitely not helping that. Still don't know if we have an appointment or not.
