Kay Manufacturing Company interview questions

interview was easy no pressure, basic questions. after interview I shown around the work area/machines, they then immediately sent me for a physical and drug test and also scheduled me for a four hour test in Markham for the following Monday at 8:30am..after the test it took about a week for someone to call me, I missed the call but they did leave a message offering me a position..but when I tried calling back the caller's name was not in the directory and she did not leave an extension, so I sent her an email letting her know I could not get a hold of her through the directory, I waited 5 days no response. so I sent her another message on Friday, just in case she over looked my email, well to date I have not received any form of a response from anyone at Kay... not even a letter informing me that they changed their mind, or they are done with the hiring process .....very UNPROFESSIONAL to leave somebody hanging.
