So just disputed 3 late payments from cap one before reading up on here. Did I make the mistake on disputing online as opposed to snail mail? what are the disadvantages to online disputing?
Hi and welcome
There is no advantage in online disputes, other than that's more convenient for CRA not having to deal with high volume mail.
Consumers probably think it's easier to do it that way.
Whenever possible, submit your disputes in writing via certified mail, especially if documentation supporting dispute was submitted
