Perhaps something is being lost in translation because I am not understanding your comments.
Aliexpress did not have the kit you payed for in stock. Fair enough, this has happened to many of us. Your expectations are because they do not have said kit in stock, they should sell you another product(s) of equal or greater value for the same price. And such product(s) must meet your subjective performance standards (which has yet to be identified).
Aliexpress asked if you “would mind choosing a replacement” and suggested 2 other kits. You do not want what they have suggested, but instead of keeping communication open you have taken to the internet to express your dislike. Not very productive.
You have not mentioned what Aliexpress will do with any remaining balance should you choose a cheaper kit. You have not mentioned whether they will give you a full refund.
You further stated that you have had past dealings with Aliexpress eluding that you understand the perceived risks involved with dealing with a grey market vendor but yet are surprised and disappointed when they respond to you with suggestions.
You can’t purchase the Revenger kit because they do not have it in stock. A stand alone mod is not a kit and Aliexpress is not obligated to give you something that cost more than what you initially paid for! Your choice is to work with Aliexpress on making another selection and negotiating any differences in cost or request a refund.
Vaporesso has nothing to do with this. Aliexpress is probably not even a qualified vendor to which you may not even receive support from Vaporesso (I am guessing cause I do not know). And if they were a qualified vendor, Vaporesso cannot make them sell you a more expensive product for less.
Dude you really don't seem to know much about how Aliexpress works, let me share what i know.
Aliexpress = Ebay same thing they don't sell products. They "rent store space" just like a mall. Everything you buy there you buy from "independent" vendors that not tied to Aliexpress or Ebay but if those sellers want to rent the space they need to follow some rules and guidelines that Aliexpress and Ebay have and enforce pretty strictly.
The store i bought the kit from is advertising itself es Vaporesso Global store so i assumed (shouldn't do it but i did) it's Vaporessos store on Aliexpress so i hold them to an even higher standard as they are not just some random seller, they supposed to represent Vaporesso and their standards.
True my reaction was hot headed and not thought thru i did write a new message apologizing for my rude behavior.
On Aliexpress a refund is guaranteed there is no if never happened and the swap doesn't work like that, nothing "official" they just send the other product instead, it did happen a few times but it was a satisfactory swap.
Usually Aliexpress doesn't need to step in, most of the time i deal directly with the seller to come to some sort of agreement, only if that doesn't work then i ask Aliexpress to step in but only as a last resort if the seller is extremely uncooperative or too rude (rare but happened).
Yes the mod and the tank cost more separately but it's just to us the customers to the company the cost dif is very small as there is a bit more packaging but that's negligible. Especially compared to customer satisfaction.
Aliexpress is not a gray market when you know how to navigate it and minimize those risks.
