Good day Abe,
I see based on the notes in my system that your team does offer great, accurate and professional updates. Thank you for that! You are able to requests and get a premium rate for the service you provide (i.e. we pay for what we get) that differs from your competition as you described.
Some thoughts about Cooper (we have worked with them for quite a while and are still working with them). I believe they are short staffed in the office. Adam can be 'difficult' at times and unreasonable at others. Rob Cooper is great and usually helps if you bring a problem to him.
All that being said, this provider offers rates that are difficult to walk away from. Along the same lines as 'you pay for what you get' - lower tolerance for included time at pickup and delivery (we are often paying waiting time but unable to collect - see my many posts about 2 differing contracts at work), less detailed updates and sometimes longer service times (I've been fortunate and have not seen the delays you have).
All this being said, 'this is LTL, what do you expect' is an unprofessional answer and comes from frustration, inability to come up with a detailed reply to satisfy you and frankly anyone who speaks that way to a customer should consider their choice of career. I can see why you made the decision you did!
Keep well Abe,
Mike
