Business ProfileforSaia LTL Freight

Saia was to deliver 8 large pieces of equipment for my business. It was scheduled to be delivered in mid September. I called them to coordinate the date and time and they said that they could not deliver because they do not have (1) a flatbed truck and forklift and (2) men to deliver. They told me I need to either carry these packages off thier truck myself (I am a 5 ft 3 person) or come to pick up with a U-HAUL. Basically, I need to take my time and money to do the job that they were hired to do. I was a bit confused because somehow they were able to get the packages on their truck and they accepted the order, so why all of a sudden are they not able to drop it off? They then told me that they will send this package back to ** and there are charging overnight fees for holding the package. I told them that they will have to speak to the company that hired them as a shipper because as far as I know, I paid for shipping and expect the package to be delivered. I called the company I ordered my shipment from and they are as confused as I am about this. Now, they have to pay a high price to get my shipment back. This seems like a ****** more than a business deal. I need to open my business but cant unless I pay a large sum of money for shipping, which I already paid for and never agreed to pay more. I had two packages delivered by ABF freight with a flatbed truck and forklift with no problem. If they are a delivery and freight company, why cant they actually deliver a large shipment? I am at my wits end here.
