I am not sure where this should be posted. I was thinking that there's a app called tapAcall, basically records phone calls (I am sure there's are better ones w/o fees). What if I were to record convos with citi or hyatt for example were there reps promise something and then they of course say no such thing etc (just a example citi told me even if I have aa card then I can get the executive card and bonus, not saying it's not true but would like to have a little backup). Can I use it against them? How would I go about it? Did anybody ever try this? Do I have to disclose that I'm recording the call to the rep?
