Sorry for any delay.
OK - being charged that much sounds like you may have NOT been dealing with Time Warner directly, but perhaps some other 3rd party service company. It also sounds like in "fixing" the internet connections, they may have somehow "messed up" some of the setting in the "modem" that provides ALL of your services from Time Warner (Internet, phone, TV?).
So what I would recommend is that you contact Time Warner Support directly, either by using a working phone (at 1-***-***-****)
- OR -
go to their contact us page (linked below) and use the "Chat with us" link at the top of that page. NOTE: I'm putting in the FULL link below, which should help get you directly to their page.
NOTE: Sometimes "resetting" the modem by unplugging power from the modem for 2 full minutes, and then reconnecting the power will restore proper operation - IF this is a modem "configuration/software issue". But if something has gone wrong with the HARDWARE of the modem, it may have to be serviced or replaced by Time Warner. That is why I recommend that you contact Time Warner support DIRECTLY - to have them look into the issue(s).
Please let me know what you find or if you have any more questions about this issue.
If this has answered your question(s), please take a moment to rate MY service level (5-star is my goal) so that I get credit for my time helping you with this question.
You should see some "stars" to do that, but please let me know if you do NOT see them (you may have to scroll UP or DOWN) or can not use them.
Thanks, ***** *****
