POPxo UI Developer interview questions

Had applied through an online portal for jobs. Had a telephonic conversation with a senior person at popxo. He called me over to their office.Had a nice little discussion about my projects and job description. He told that they'll give a small task to complete. They never responded back despite constant reminders. I had a telephonic conversation with the same person regarding task.He told he would revert in few days and he never did that. Also sent him a mail regarding that,still no response. I am unhappy with the way they treat the candidates.They spend money and time to come to your office.At the very least a feedback is expected.
