It's been one and a half years since I've worked for my former company. They still owe me 2 weeks of pay and reimbursement for gas mileage. Everytime I send in the papers, they say they never received the fax or mail. The person that was supposed to resolve the issue since resigned and I haven't been able to reach the new person in person, just her voicemail, which I have left messages before. What are my options here?
