Unpaid invoice

I did work for Strata Drilling on 2021/01/20 - repair of a hydraulic press. I sent the invoice and after 30 days I sent a mail and was told that I was on the pay schedule for Friday 2021/02/26. Till today I have not received payment. I just want to caution suppliers and customers to be careful of using Strata Drilling as they do not pay. The amount owed is a paltry amount and this raises a red flag as to the ethics of Strata Drilling.
