Saint-Gobain Engineer interview questions

It is unbelievable that this company does this in the interview. I got the phone call from HR, and was told to do an onsite interview without any phone screen interview. And she told me that the tolls, gas can be reimbursed. I emailed her after the interview about the position and the reimbursement, no response. Then I called her instead and she said she was busy and would send me paycheck in the coming week. After one more month, I received nothing. She doesn't reply my email or answer my phone any more. If you can't reimburse, you can tell me after the interview, it is ok. but I can't believe that the way they work.
