How to cancel Apple Care for iPhone?

The sales associate said I can cancel it whenever, and I'd like to do so before I get my first bill in two weeks.

If you cancel within 30 days of purchasing the agreement, you will receive a full refund less the value of any service provided under the agreement.

If you cancel more than 30 days after purchasing the agreement, you will receive a pro-rata refund based on the percentage of unexpired coverage in the agreement, less the value of any service provided under the agreement. There's also a cancellation fee of $25 (USD) or 10 percent of the pro-rata amount, whichever is less. You should receive your refund in about 4 to 6 weeks.
