I am receiving a volume of calls from this number. They divulged an old address of mine and this is perhaps because they are not actually Charter, but rather someone who has acquired Charter records and is trying to solicit credit card information from Charter patrons.
I have blocked this number and will report it to the proper authorities if they can find a workaround.
I get a call from the number about once a week on my cell number. My parents received a call on their landline last week. The caller says they're calling about my microsoft computer being infected & wanted me to turn it on to help me repair it.
