"I was app-alled by the appointment service"

The other day I wanted to book an appointment with a nurse or doctor, I wasn't fussy which. To avoid the ludicrous telephone lottery, I got up early and walked to the surgery, arriving just before 8am, sixth in the queue outside. (Walking isn't easy for me but it's good exercise, right?) I don't have a smartphone and my mobile packed up the other day. The receptionist said she'd book an appointment for me via the app. That sounded rather weird but I went with it. Then she indicated that I'd hear from the surgery. I asked how since my mobile was broken and she said someone would ring my landline. So I walked home, really at too fast a pace for me, in case I missed the call. I waited by the phone until 10am, then I rang the surgery, concerned that a message might have gone to my broken mobile phone. The automated message told me that if I'd applied for an appointment via the app (which I clearly had by proxy) that I'd hear by the end of the day. So I prepared for a long wait within earshot and reach of my landline phone, my plans for the day upended. Now, I wouldn't have minded that quite so much if I'd phoned for the appointment, but I'd walked an uncomfortable walk to the surgery and back to get an appointment in person. This is ludicrous and seems very discriminatory to anyone who doesn't have a mobile phone for whatever reason. Such patients apparently might need to rearrange their whole day in order to not miss their appointment call-back? I got a call-back at 11 am with an appointment to see a nurse, so 2 1/2 hours of my day was wasted which was somewhat of a relief - it could have been way worse. This needs to change. We rightly aren't supposed to waste doctors' and nurses' time but our time is valuable too.
