I just receive a call from who said was the supervisor of this company, unfortunately I was kind of confuse with his question, and he was ver...very rude ...and hung up on me with is very unprofessional. I tried to call him back to obtain a human resources department. And he just hung up on me again. Thank God I need a job, but I think I deserve some respect as a person looking for a job.
