Sigma has provided services for the business I work for before. Dave was a great technician. The owner, Thomas, however, is another story. For some reason, the admin at the time, misplaced an invoice ($100-something) and it went unpaid for 2 years. Sigma and Thomas never reached out to us for payment so imagine our surprise when we made another service call. Thomas chewed out our new admin (who wasn't even employed at the time of the last service call) and decided he needed to pre-invoice us. That's fine. The technician came out for 10 minutes and we were billed for an hour and a half. We called back to see if we'd be receiving an updated invoice and Thomas informs us of his time minimum. We agree to pay the invoice and Thomas replies, Well if you look at the first invoice that ya'll didn't pay for 2 years... Why the hostility? We already apologized for the missed invoice and agreed to pay the minimum on the new invoice. It wasn't like we were always delinquent. It was ONE invoice out of how many times we've made service calls with Sigma? Why didn't your accounting department call us to reconcile the invoice in the last 2 years?
