I mailed a package using UPS online and reported the dimensions as 44 x 36 x 5" (it weighed 21# but was 41# by dimensional weight). Several days later I received a Notice from UPS for additional charges to my credit card because they claim my package was 44 x 36 x 7" thereby increasing dimensional weight to 57+#.
In actuality, the package was 44 x 36 x 4.5" and I still have part of the box to prove this (originally the box was too long so I cut down the length). I will contest this with UPS and my credit card company, but no doubt they are doing this to others as well.
This calls for a class action suit!!
