Globant Quality Control Analyst interview questions

I was referred by my friend at Globant. Received a call from HR, he asked me about the current salary and excepted salary. I had given him all the details on phone then he sent me a Google form asking for the same details. Interview was scheduled on Saturday as it was a virtual drive. I cleared technical 1 and technical 2 rounds and received an email asking for documents. I submitted the documents and did my hear anything from them. I called them in the next week asking for the feedback. He replied ' Congratulations you have cleared the interview, but we cannot offer you what you are expecting and cannot even offer you the same salary as of your current salary'. This is completely unprofessional behaviour and wasting someone's time.
