I received this email today.
Thank you for accepting this assignment. Unfortunately we have to cancel a large number of shops as we were given an incorrect list of locations. You do not have to do anything else. We will take care of the cancellation. Because this was initiated by us the cancellation will not have a negative impact on your shopping history.
Please understand that this email is being sent to a number of shoppers; you are not the only one. This cancellation was necessitated by the Client. It has nothing to do with anything you might have done or because we are trying to take shops away from you.
We apologize for any inconvenience this may cause, and we appreciate your understanding.
