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 called based on the other comments and it it Charter telemarketing. They are calling me several times a day like most other people never leaving a voicemail. I never do business over the phone with Charter anymore, they screwed things up the first time I tried. I told them to put me on the do not call list and said it would take 45 days to go into affect, which I think is probably just to make me forget I told them to stop calling those 45 days ago. I said that if they call past that 45 days I will make a formal complaint. The guy I talked to was very nice so I felt bad threathening if they didn't stop calling me immediately. (Don't be like me)
