Our customer service staff is available by phone Mondays-Fridays from 8am to 5pm and on Saturdays from 9am to 6pm. We also answer the phone 24 hours a day, 7 days a week, should any emergency arise. You can always give us a call at 580-5800.

Here are a few tips to help troubleshoot your equipment, if these don’t help, certainly give us a call! It is important that you leave all of your equipment plugged in and turned on when you call us. This will help us figure out your situation.

No dial tone
We would suggest checking to make sure the phone is still plugged in, or if it is a wireless handset, that the battery is fully charged and working properly. If you are still having issues with getting a dial tone, please call our office and we will troubleshoot the issue for you.

Long distance calls aren’t working
The first thing we would check is to make sure you have long distance service set up on the account. If you don’t know for sure, give us a call.

Do-Not-Call Registry
The National Do-Not-Call Registry has been established to offer you a choice about receiving telemarketing calls at home. Registering will stop most telemarketing calls but it will not stop calls from certain non-profit and political organizations and calls from organizations with which you have established a business relationship.

Consumers can register their residential telephone numbers, including wireless numbers, on the National Do-Not-Call Registry by telephone or by Internet at no cost. The number will be on the Do-Not-Call list the day after registration; however, telemarketers have up to 31 days to remove the number from their call lists. You may register up to three numbers at one time if registering on the Internet. If registering via telephone, you can register only one number at a time and you must call from the telephone number you are registering. A number can be removed from the Do-Not-Call Registry at anytime.

To register or remove a number from the Do-Not-Call Registry call 1.888.382.1222, for TTY call 1.866.290.4236 or register on the Internet at www.donotcall.gov. Additional information can be obtained at www.donotcall.gov.
