After waiting around 2 months without any updates, I contacted Hhampuz in this forum. He helped me a lot, he talked with his guys at duelbits and came to the conclusion that they can retrieve the funds at some point in the future so they have credited me with the lost amount. I received it today and I withdrew it successfully, and they don't charge me any fees. Below is the proof they credited the lost amount which is $2418.9 to my duelbits account.
First of all, Congratulations to successfully recovering your lost funds. This is expected since Duelbits is reputable here and we have strong connection to the management since manager Hhampuz has a regular connection with them through their long running signature campaign here.
Please lock this thread before you leave to avoid being spam by other user that doesn’t read updates. Congrats again.
