When I tried to cancel my account, I was presented with a "Special Retention Offer" that listed several major components of their service (that I already had as a Business Plus customer), detailing max file sizes, bandwidth, etc. and then said "In other words, you get the same great YouSendIt service at a lower price." Figuring I could still use the service from home, I signed up for this deal, only to find out shortly thereafter that several major components of the Business Plus plan were *not* included in the Special Retention Offer, including the big one, the Dropbox (which allowed people to send *me* things). Of course they'd already posted the $20 charge to my credit card, even though I had weeks to go on the old plan, and I had to wait until that time to cancel my account (because my account was already in a "pending downgrade state"), and then they refunded the $20 as a "service gesture".
Next time I'll use the "NO THANKS" button.
