ok so a while back while i was in san diego i had a wireless internet card for my computer and it was connecting to mexico verizon charged me for roaming and said that my computer prompted me to let me know they tried charging me a couple grand i told them i had not left the states and that i could connect from my house told them to send a tech and i would show but they told me that is impossible and that i need to pay i then finally got paper work together showing that i had not left the states and they waived said charges but they did put it on my credit report cause i had refused to pay while we worked out our differences this happened in 2008 is their a way i could go about fixing it should i call and complain to verizon or go throught the credit unions?
