Having made an appointment on a Saturday afternoon to see a girl the following Monday morning, I turned up about 15 minutes early. I texted her 5 minutes later letting her know I was now parked up nearby and requesting the flat number. 10 minutes later, having had no response I called. It rang through to vm so I left a message. At 10 past I rang again and, when it went through to vm, left one saying I was offskl.
Luckily for me plan b turned out to be a blinder, so my frustration with plan a quickly evaporated.
I suppose this is technically being turned down, perhaps because she'd double-booked, hadn't made it into her 'office', or for whatever other reason.
