Would you spend an hour on the phone with a guy you are not interested in?

So, here is the situation: I met a girl (25) online and we spent some time texting back and forth. Then we went out for a few dates (6 in total). When I invited her over to my place at the end of the last one, she said she wanted and also didn't, because she has a lot on her plate right now. I mean, she has talekd about all the things she has to take care of before. I was like "OK, no worries". After the date she texted me to thank me for a great time. Few days later she suggested two days she was available to meet up, but had to cancel both due to some medical stuff I had no reason to doubt. I told her, it was OK and that she should let me know when she would want to go out again. Since the text intensity lowered and she did not suggest any new time. So I decided to call her and we had two phone calls - one hour each. But she claims she doesn't have time for at least two weeks now (one week is her vacation abroad). I honestly don't know what to make of this. Would you spend so much time on the phone with someone you are not interested in?
