I am reading reviews of this company which we have been using for a few months now. It seems there is a pattern (get charged $1000 "by accident", rates being raised after a couple of months, not being able to get anyone on the phone). I thought the overcharge was just a mistake on their part, but after reading these, I am seeing that this is a practice of theirs. I was told I could no longer ship anything because I hadn't agreed to their new rates which we have never received any notice about. We haven't had any issues with their e-commerce portal at this point...just their LTL service. The rates seemed ridiculously low, but I guess it was either a bait and switch or they don't have a clue what they are doing. Either way, not good.
