Horrible company. This is what a quick Google AI summary has to say about it:

OnTrac reviews are overwhelmingly negative, with widespread complaints about delivery issues, including packages being marked as delivered but never arriving, items being stolen, and inaccurate tracking information. Many customers feel OnTrac's customer service is unhelpful, and some online forums even advise consumers to boycott retailers that use the carrier for shipping.

These clowns have twice lost, mishandled and/or stole the same order. I am right now yelling at the seller for using these clowns. Made the company promise to reship my items using a different carrier.
