If it is still tobacco, I would call and clarify with them SJeane, if it is Nicotine, unless you vape 0mg, it is nicotine... and if you vape 0 nic I would still call and clarify.
If it says tobacco now, doesnt mean it wont change to Nicotine soon, and if vaping 0mg nic is okay now, then they decide its not later... well... idk, my stand point is, it may cost you more to be honest and straightforward with em, but if it doesnt, if say they (at this time) decide you are good and later change their minds, at least when they come to you upset (possibly not saying its going to happen) you can tell them to check their recorded phone records, and that you had already informed them...
just my
i prefer any call center that records my calls... can make me a huge pain in their ends later if something goes awry...
