Does anyone know how to contact the DeepSeek support because i was charged 2 times when i made a single transaction two months ago ?

Does anyone know how to get in touch with DeepSeek support regarding a billing issue please? On my DeepSeek purchase history, only a single transaction appears for that day, but our company bank statement clearly shows two distinct charges for the same amount (from 2 months ago). I tried reaching out via the only contact option available on their dashboard nearly two weeks ago, but haven't received any response, not even an automated confirmation email. At this point, I am requesting either: A direct refund of the duplicate charge, or The amount credited to my DeepSeek balance, along with an official invoice backdated to the original transaction date. I need to submit and balance all my company expense reports within the next 10 days, so this is getting urgent :/ Any help or contact email would be greatly appreciated! Attached is a screenshot of the interface where I submitted the initial request. preview.redd.it/3m3xs2wlnvqh1.png ty !
