I have been doing transcription work for a law office (how ironic, huh?) for about several months now. Up until now, they have always paid me within 30 days (which is what I have on my invoices). Once, they were late on a payment and I sent them a fax with the invoice and they promptly paid me. Within the last 2 months they have not paid me. I have sent them reminder faxes and called their office and left their accounts payable messages (she never seems to be in) and now IDK what to do to obtain payment. I never had them sign a contract nor did they have me sign one, so I'm not sure if that gives them the right to do this to me.
Any advice would be greatly appreciated. Thank you so much.
