Query: Pump broke before finishing the ball

The pump already looked fishy, it had some remains of contact glue at the top end of the pump. 15 minutes ( 65 cm on the way ) the top part comes off..I guess with contact glue I will be able to fix the pump, still...The ball itself so far holds well, not sure if one is supposed to sit on it when its not fully inflated though..T.
