ohh Jully. i've written this exact post many times myself. I know exactly how your feeling. Usually it turns out they have a decent excuse and then you feel stupid. All i can say is please please don't stop going back, as much as you feel uncared about, the truth is they do care. Once you hear his or her excuse it will be ok. or if they don't have one and they apologize, it will be ok. tell them exactly as you have said here. i really do understand your frustration.
