You should measure 350 feet of fencing
I ordered 348 feet of 5 foot high fencing. When I questioned if the product I received was actully the product I ordered (due to size labeling on the box), the solution offered was "unroll it to measure it and then roll it back up to ship it to us, if it's not the proper length". When I pointed out the asininity of that, I was told I would be contacted by customer service. And I was via email. And they told me the exact same thing over and over and over and over. Obviously this company does not even use their own products or they would grasp the utter absurdity of such a solution. The final answer was "that's the dimension of the packaging". More asininity.
