Bombay Pantry interview questions

Went for an interview which went well. The "hiring manager" Simarjot advised me I would start next week for 2 hours of training and advised me to wear black clothes as my uniform. She stressed if I was serious as she had experiences before of people backing out and I advised yes i am very serious and she can rely on me. I stopped looking for work after securing this job. On the morning when I was to start I received a message to say they had found someone else. I think this is extremely unprofessional and very irresponsible. If that's how Bombay Pantry treats people I am glad i did not start with them in the end. I would stay away from this company as they are not rely and not honest.
