I did that with carbonite. I was on record as I recently tried a trial period with them. I wrote them back and said I would never use them. I doubt that it did any good, but at least they got a message back. To hell with them. Rush made their company.
“Nevertheless and on Wednesday, Carbonite rose 3.11% to $8.61 (CARB has a 52 week trading range of $8.21 to $21.10 a share) for a market cap of $216 million but the stock was down 11% for the first six days of March, down 22% since the start of the year and down 30% since its debut last August.”
