Bank of America has had my husband 's and my SSN wrong in their system for the past three years, and refuse to consult my original loan documents to correct it. My credit has been impacted along with my sanity. For the past three years, they have mailed us letters in XX/XX/XXXX advising that our Tax Identification Numbers are incorrect, and request that we complete a XXXX form. I 've already done this, and I 'm not comfortable sending this sensitive information via snail mail AGAIN. I 've contacted their CS phone number to discuss this issue, but was only told that my issue was being referred to " the back office '' and advised that I would receive something via mail in 7-10 days. Then, I also tried writing to them via their website, but was merely told to call CS again. The correct SSNs are contained in my original loan closing documents, which BoA has, so I expect them to consult their records and update my account information accordingly. Stop being lazy and requesting me to furnish information they already have on file.
