A company representative explicitly said I would be receiving my traveling reimbursement by 30 Nov, but I have not yet received it.
In addition to this, they sent me an offer via email, I said I would accept it contingent on looking at the contract, and they haven't sent that either. All this communication happened about a month ago.
As a non-native speaker, I'm not sure how to send a polite but firm email reminding that they're due to send me reimbursement and the contract.
