I joined an MNC a few days ago, but they mentioned an incorrect joining date in my offer letter. I requested them to change it, but they still haven't made the correction. They keep telling me that they have been working on it for the last 15 days, but no solution has been provided yet. I haven't received my salary, and they haven't created my PF account either. Should I consider leaving the company? I now have another offer letter from a different company. What should I do? I would appreciate your suggestions.
