Help with android market app removal

[gayeb]

Hi all hoping someone can help,
Im new to the android market I have downloaded some apps to my android market account online with my laptop, but wish to stop them from going on to my phone as it is using all my credit at the moment I have just disabled the internet data on my lg optimus spirit the download has stopped of course but I wish to remove these apps from my online android market without using my phone is it possible?? Becuase as soon as I enable data on my phone it's using all my credit.

Thanks
