Query: weak construction

This size screen is long enough that the flimsy method used of attaching the inner roller to the endcaps causes the plastic bits to be broken during shipping. I just recieved my second screen from amazon after the first was broken by ups(once the plastic part it broken it will not retract) and this one shows the same damage. Amazon customer service was great about sending another screen, but I fear that the manufacturing weakness will make any further shipments a waste of time. Elitescreens customer service is disorganised and not helpfull.
