I just had signed up with another company to store my crypto currency in. I had used Changelly to transfer a portion of 1 currency to the other and on my own fault didnt realize the fee attached would need to be factored in additionally to the total being sent. I had seen the transaction showing failed. They told me it was because the amount wasnt enough to cover the fee but could apply it the amount and push the transaction through for me. I am very pleased and the enthusiasm and attentiveness to help. Very satisfied!
