Query: Not 65cm

My complaints about this ball:--At full inflation, with the ball extremely firm, the diameter measured only 55cm, not the 65cm listed on the box.--The plug could not be fully inserted. The end stuck out a quarter of an inch and would not go in further.--There was an ugly black and green logo printed on the ball which was not shown in any photos.--When fully inflated, the color/texture of the ball was uneven--with drip marks visible and patches of varying thickness in the material creating a mottled look.I will be returning this product.
