Citibank's Charge Dispute Forms Have Two Different Addresses

I’m challenging a charge on my Citibank card right now and have to fill out paperwork for their records. The second page of the form I’m filling in tells me to mail the form back to PO Box 6035, The Lakes, NV, 89163-6035. The self-addressed envelope they provided me with to mail the form back in? It has an address of PO Box 6013, Sioux Falls, SD, 57117-6013. A bit different, don’t you think? I’m just going to copy the form and mail it to both. I have 10 days to get this back to them, so I’m sure that having two separate addresses helps to deny claims i.e. “We never got your paperwork.”

Maybe sneaky, maybe honest mistake, either way, just another reason you definitely gotta scrutinize every line of fine print when you’re dealing with a bank.
