Subscription Cancellation

We are developing an app which has an In App Purchase for subscription, we have the application in tesflight, and the subscription is done through apple developers account in the app store, now we are trying to cancel the subscription, we just keep getting an error message in app store stating "your request is temporarily unable to be processed".

we need to cancel this subscription for us to test our application properly.

any help on this would be appreciated.
