Maybe you should contact Experian.
I would look up their website on line though.
It could be a scam of someone PRETENDING to be Experian.
FYI, my credit has been frozen for several years because I was part of the Experian hack of SS #s.
I froze my credit so that no one(not even me) can take out any credit in my name.
It was easy. However, I did actually have to do it in writing with one of the four credit agencies.
They sent me back a letter with a code number that is now in my safe. I have to give them that number to unlock my credit in the future.
I had paid off my mortgage. Have no car loans and already have a Mastercard, AMX, Lowes, Home Depot. I do not need any more credit cards.
Did you know if you freeze your credit...there are now four (4) agencies where you have to do it?
