This might be a misunderstanding between the two parties. I explored some of the ones you both present.
About the Green token main chain. If we refer to token trackers, what we can see together is that the ERC-20 network runs first than the polygon network which means the ERC-20 network is first the GREEN main chain.
ERC20 network - 1st transfer is 11 may 2018
Polygon network - 1st transfer is April 14, 2021
Tokpie's claim in this case makes more sense to me. Based on one of the screenshots of the conversation
in this post, a deal was struck on April 6th to be listed on Tokpie and other services before the polygon chain GREEN was created. And the GREEN Team also can't insist that Tokpie has to support polygon networks, although technically your reason is justified but you don't list your token to support 2 different networks in Tokpie.
About being listed on Coingecko (CG), I don't know how experienced Tokpie is with this. I think you are too confident to give listed offers only 24 hours. Even more so if you only make your exchange only as data preference. The Green team should also realize this is too easy to be true for (sorry to say) a low quality project and you should ask for a money back guarantee on the initial agreement if it doesn't work out in time.
It will be a CG confusion, when the main network is changed to polygon, on the other hand the Tokpie team might just add market list of GREEN with their own exchange which doesn't support polygon network. That's why GREEN is hard to be listed there.
As a suggestion to solve the problem for both of you, then consider these things:
Firstly, @Tokkie however you have failed to list this coin on CG, even after 24 since the April 6 email was sent. You should return the money immediately consciously at that time if you are a professional.
Second, @GREEN you can't actually claim a refund because there's no agreement about it, instead you're asking for more than the original agreement.
Although this attempt at listing was not successful, there is a process that must be rewarded with money even if it will be lower than what was originally agreed. I don't agree if the return has to be 100% and I don't agree if there is no return at all. At least a few percent, depending on how far the process was.
Regarding refund. I propose about 50% refund twice. Twice got note: no refund.
I understand your position: no agreement - no refund. In same way agreement was to list 24 hours to CoinGecko and 72 hours to Etherscan, not telling about CoinMarketCap. No of this wasn't done. We ask about 50% refund twice to close questions from us.
100% refund we asking only now (its not more, than we sent). Because their work completely ineffective and after two 50% refund rejects we spend time on this topic.
Regarding main chain of Green Token. When we tell in our Telegram Group about Polygon is main chain we meant, that there most exchanges count at that moment and even now. In same time Ethereum network ERC-20 token never stops working. Main reason, why it has no activity, that is 100$ fee for simple transfer or exchange is a little bit insane for any user, that use token of not so huge project as ours.
To Polygon any user can at any time deposit their ERC-20 tokens (Trade there with ~$0.01 fee) and withdraw back to Ethereum and trade on it also.
Hope its clear
By the way we never ask about supporting Polygon network on Tokpie, the ask was only add contract address of GREEN to Coingecko, while list, what was accessible from the beginning and its not confusion for Coincgecko (as a lot of tokens support both chains and Coingecko track it). Anyway even Ethereums contract was not added to CG. Polygon should be second step.
