Is it scam mail, someone order stamps that I did not order?

I just got a text telling me I owe money on my EZ pass. Thats impossible since they charge my credit card every month.

By the way, these stamps they sell so cheap, is a scam in itself. The are counterfeit.

As long as you did not open anything, your Ok. Delete it from the email and then again from trash.

You should also put a "fraud alert" on all your cards.

Did you click on any links that were in the body of the email or respond by hitting reply? Did anything automatically download on your computer when you opened email?

If you only opened the email and then deleted it should not have ant adverse affects.

Monitor your bank accounts and credit cards and report suspicious activity.

I would say ignore it, but then I didn't SEE it. So I am uncertain what your email said, accused you of, attempted to charge you for.
I would caution in general not to open links anymore from anyone, and not to buy into anything that even begins to sound like "We have a package for you". "We have your stamps and you owe us ...." Blah blah.
Learn to be very suspicious.
They will come at you with any old story, and they can make their sites look exactly like your local bank, or the postal service.
Good luck.

Be careful, this is a known phishing scam.

Good thing you deleted the email.

Did it have or did you provide ANY information; Personal or otherwise?

If you did not, you can not be charged, they have no information.

If you fell for it, I recommend getting your credit card company or bank on the phone and report a fraudulent charge, when it shows up. This is the way to stop the charges and get whatever company is running the charges on your CC or banks radar, they have better capacity to report and stop these scammers.
