I think they are saying someone will pay for support, use it, then cancel the subscription. The assumption there is that you offer a refund for the service, which I don't think is necessary (Especially once they have used a support inquiry.)
Apple in-app subs let you "cancel" but only in the way of not paying for the next renewal, so it is a widely used model already.

exactly this.
Just cancel his subscription the NEXT month, and you solved the problem, financially and technically :)
And who would HATE this proposition ? the spammers :)
now they won't be able to do what the OP has suggested they might do (pay -> get support -> cancel ):)
If you cancel the subscription, you won't get support. I don't understand your point :)
