Feedburner won't stop sending blog post email alerts

[Sophie Cay]

Hello,

I thought Feedburner ended in July. My subscribers got a Feedburner email for my latest mid-August blog post. I tried to delete the feed and got an error message:

"Feedburner encountered some sort of error trying to performing the task …"

We cannot put inline screenshots here so I can't show you the exact steps. 

Now how do I delete my feed subscribers???? 

Thanks,

Kay
