I am trying to deploy one class which has implemented Schedulable interface.

But when I try to deploy it using ANT I am getting the following error :

"Schedulable class has jobs pending or in progress".

I am waiting for this to get resolved since more than 48 hrs and it doesn't seem to resolve.

What can be done in such case? How to deploy it to production? I tried to deploy by making packages but could not since the components in the package already exist in production and gives an error when I unzip the package. Please suggest what can be done in this situation.
