How Do I Make A Payment On Line ?
The safest way that I know of to make an online payment is to set up an online account with your bank so that you can pay your bills through them. Some companies online services may not be very secure and could be hacked, getting your credit or bank card account number. If you set an account with your bank, they are insured and so tend to keep a better eye on your account. They will also cover any losses to you because of identity theft if it occurs through their services.
