Can you please post the log of your FTP session?
It's very likely that you do not have sufficient permissions to delete the files. Did you already contact your webhosting provider regarding this issue?
Regards,
Mat
Thank you for your fast response Mat.
I have opened a support ticket and made a phone call to our webhost provider - in Australia, they only provide support Monday to Friday and even then the level is poor...I am also in the process of changing providers.
log is as follows...
