CALIFORNIA -- Fax.com has an annual plan that charges you without billing in advance:
"If you subscribed for the Services for a fixed number of months (e. g., an annual plan or multi-month plan), your pre-paid fees are payable in advance and are COMPLETELY NON-REFUNDABLE. In addition, your pre-paid fee for the designated period immediately following your pre-paid period will be PRE-AUTHORIZED AGAINST YOUR CREDIT CARD OR DEBIT CARD LIMIT and will be immediately charged to your credit or debit card, without further authorization from you, upon the expiration of such pre-paid period, unless you provide prior notice (in accordance with the Company's cancellation and verification procedures, as may be established by the Company from time to time in its sole discretion) that you have terminated this authorization. Such notice will not affect charges submitted before the Company reasonably could act on your notice. "
So there is no advance notification that the charges are coming and if you don't give them enough notice, tough luck. They can charge you without authorization and you cannot revoke or get a refund. This is a TRAP!!! That's what happened to me. It shows that this company is run by crooks who trap their customers. Stay Away!!
