Sure, here's a revised version of your text: During my initial phone interview with HR, there were issues with the connection and the call kept breaking up. I kindly mentioned to the interviewer the connectivity issues, and she became agitated and treated me with a negative attitude, replaying everything twice. Regrettably, given her unprofessional behavior, I stated that I wished to discontinue the interview. I didn't want to continue speaking with someone who treated me poorly and was causing frustration due to the connectivity issues.

The interviewer was 15 minutes late, cold and had poor interview technique. I was offered the job but I declined - I would not want to work with this person.
