Remember to be diligent about checking your credit card bills and other statements. Additional charges may be added to your bill by either human error or just as a test by scammers to see if the charges go unnoticed then you r account may be charged for a larger amount at a later date.
Double billing and errors happen. Check your bill often, even between payments to see what charges are being added to your bill. If you believe that you are charged twice for something that you ordered, contact the merchant to try to straighten out the situation. Generally, reputable places can check their records. If this does not work, then go to the credit card company.
Notice a charge that you did not make? Directly contact your credit card company.
Phishing scams are on the rise, because of the economy but some crimes are either not reported or not detected for a while. Even additional charges may be added to your cell or home phone bill. Always check to see if additional services are added mistakenly. This is especially true if you have automatic payments charged to a credit card or deducted from a checking account. I had an automatic deduction made from an account for a mortgage before and more money was being taken from y account than it should have been. The amount was very small and was added to my mortgage as additional principal. Sometimes the amount deducted may be keyed in incorrectly and could make you have to pay additional late charges. If you have proof that you have automatic payment and that it was an error on their end, then you may have to go through the hassle of straightening it out, but you will receive a credit.
Be diligent in your own finances.
