I am sorry to hear about the carrier’s delays with your delivery for whatever reason they have. Once a carrier is locked in that does not guarantee a specific pick up or delivery date/time. All it guarantees is that your vehicle will be picked up within an estimated timeframe by that specific carrier company. There are too many circumstances outside the realms of our control when it comes to the carriers such as: (FMCSA driving hours being reached and the carrier being mandated by law to stop and rest for 24-48 hours, Poor weather conditions, Construction, or a vehicle/truck breakdown) In addition the USDOT/FMCSA also allows all carriers/transporters up to 30 days past your estimated delivery date to delivery your vehicle for these precise reasons and there is nothing legally we can do until that time passes. We are unfortunately at the mercy of the carrier when it comes to things like that and require our customer to maintain some flexibility around the carrier's schedules. While we do try our best to accommodate our customers' pick up and delivery date requests we also try our best to make sure every customer knows we are absolutely unable to guarantee any specific dates. We list this information on our website, our contracts, and many of our emails, it is also typically told to customers by phone when booking as well. At Mercury all of our quotes are estimated shipping prices based on the demand of any particular route at that time. The more popular the route, the higher the price to ship a vehicle. We the brokers are not the ones who set the final prices, it is the drivers/carrier companies that do. They are able to view all of the vehicles traveling certain routes and pick the ones offering up the best prices. When you shop around with other brokers to receive additional price quotes, what that does to the national board is it makes it seems as though a route is in higher demand than it actually is which causes your initial quote price to change which is why your initial quoted price could not be locked in at that time.
