A contract address is not a repository of tokens like a typical wallet; it is essentially a computer program, a set of code, that performs some function on the blockchain. If you send any number of tokens to a contract address there is no guarantee anyone can retrieve your tokens. In the case of Element United's contract address unfortunately, your tokens cannot be retrieved.
Disclaimer: ELMT is a digital reward distributed through the Element node network according to predetermined smart contracts. ELMT is designed to have utility on the Element platform for the purchase of Element products and services, although other cryptocurrencies may be used as well. ELMT is not available for purchase from Element. ELMT is not an investment product and may never have any value. Element node owners should not expect to recognize any value from ELMT other than its utility with Element. Although Element plans to undertake efforts to become a successful business, it is highly likely that ELMT's value will not correlate with the success or failure of Element.
