Can't delete spam

Hello.

I am having a problem deleting two spam comments I have received and I can’t delete them no matter what I do. Akismet has recognised them as spam and isolated them but when I select the comment and click delete permanently it reappears a few seconds later. I tried the bulk actions and empty spam. I was getting an unknown error message. Now I get the comments have been deleted, but they are still there. This is also creating a issue with Better WP security as I keep getting emails saying files have been changed.When I remove data it does it again a few seconds later.

I did a google search where I watched a video deleting the comments via Myphp but this did not work as I kept getting mysql errors. I have contacted my hosting provider.

If anyone has any suggestions. That would be great.
