I see by your profile you are 15, that makes the league a Junior league? Unfortunately, in the years I worked with the Junior program I saw this happen often. It doesn't make it right and it doesn't excuse their actions, but it happens.
Talk to your Youth Director about the current team situation. Even though they are Juniors, they need to be made aware of proper league etiquette.
When you bowl the team that dumped you, let your bowling do the talking
