Query: many many defective parts

The pole itself seems to be a solidly built, but so many of the parts that it came with where defective from day we got it that he pole was useless. The upper bolt that adjusts the height of the pole was defective from the day we got it and all but impossible to adjust. The hidden screws that are suppose to hold the pole when it is in the fixed position were stripped out. The company customers service was completely worthless, I called multiple times and each time got a voice mail account. I left several messages and my call where never returned. This might of been a good product had all of the parts worked.
