Example Citations:
Wisconsin consumers complained less about slamming, the unauthorized switching of phone service to another provider, and cramming, the unauthorized addition of services to an account. --Lee Bergquist, "Wisconsin Utilities Draw a Record 5,416 Complaints," The Milwaukee Journal Sentinel, August 3, 2000

The next big thing in telephone scams is cramming — unauthorized phone charges, often for services customers never receive, from companies they’ve never heard of.
—Jennifer Files and Alan Goldstein, “Tech Bits,” The Dallas Morning News, November 24, 1997

Earliest Citation:
Call it ‘cramming,’ ‘whamming’ or ‘super-slamming.’ Call it what you will, but Lorraine Parker calls it a ripoff. Parker was shocked recently to find charges crammed deep into her phone bill for services she says she didn’t authorize.
—Cam Simpson, “New phone scam: ‘Cramming’ your bill,” Chicago Sun-Times, October 17, 1997

Of the three terms listed in the earliest citation, above, the usage marketplace seems to have decreed "cramming" the winner over "whamming" and "super-slamming." That makes linguistic sense because this practice involves stuffing bogus charges onto otherwise-innocent phone bills, and "stuff" and "cram" are synonymous verbs.
