Complaint / review text:
The charges appearing on your local phone bills, billed by OAN Services for Telseven LLC is shady in the least, although legal. When someone dials a phone number and gets a message to call One Zero One Zero Two Seven Five then 555-1212, (notice they don't say TEN TEN 275) you will be billed 4.33 per call, plus a Carrier Assessed - Admin Fee of 1.65, plus taxes, resulting in the call for a regular DA call costing over $6.00.
If you receive such a call on your phone bill, dispute the charge by calling OAN, then have them put a BLOCK on your line (s) for 10-10-275 to prevent this from happening in the future. This will not prevent someone from dialing 10-10-XXX, it only prevents calls being made to 10-10-275.
Although the number on your bill will appear as 702-555-1212, in fact someone is dialing 10-10-275-555-1212. Trust me, soon enough there will be other 10-10-XXX numbers doing the same thing so beware and look at your telephone bill every month.
Some local phone companies offer 10-10 blocking, but there is usually a monthly charge related to that which doesn't make it cost effective.
We can thank the FCC for making our local phone companies billing agents for this and many other problems that occur on our bills.
