other package using another company.

 So we got it from FedEx in two days, no problem at all,  said Diamond.

After looking up reviews of LSO online, Diamond said this experience has made him wary.

 So you're expecting things to come, and you're relying on a delivery service to actually deliver the product, and they just have a reputation that they're not delivering at all,  Diamond said.

NBC 5 Responds contacted Lone Star Overnight to get answers.

In an email a spokesperson for the company wrote:

 We are aware of an isolated number of customer satisfaction complaints that have popped up recently. LSO is committed to ensuring the satisfaction of each and every customer, so this issue is one that we take incredibly seriously and are committed to correcting. The current challenges in the supply chain have impacted LSO and all other carriers, and the increased demand due to the busy holiday season has caused additional challenges. During this holiday season, LSO processes over 3.6 million deliveries, which is 50% higher than a normal month. Although we strive to provide exceptional service and on-time deliveries to all customers, that is not always possible. Any number of complaints warrants action from us, even if it is a very small percentage of our overall deliveries. To ensure that we get this corrected for our customers, we have set up a dedicated phone line and email for people to report issues to so that we can follow up with them in a timely manner. LSO is committed to ensuring that we are able to handle the unprecedented volume of packages that are being delivered during this peak season and are actively working to ensure that customer concerns are addressed. 

LSO also gave NBC 5 Responds new contact information for those who need help tracking their packages.

The Better Business Bureau posted on its website that it's looking into Lone Star Overnight's business practices because of a large volume of complaints and bad customer reviews.
