Lack of response

Good day I would like to mention how awesome it is when you have an agent calling you for an interview telling how urgent the interview is for tommorow and cannot be postponed for a day it must be the day after they called you for an interview, now you go for an interview and than you laterr in the week mail your agent for a response and all he does is read your email but does not respond? Because I do get notification that the mail has been opened, one agent can make a company look so bad because I cannot tell people to apply at Afrizan because if they do apply or submit cvs at Afrizan they will call you in for an interview act as if they going to offer you the job immediately and you wait months and months and you mail them and they just read your mail but no response. Actually that is pathetic to say the least.
