International Banking team missing in action

International Banking team does not respond to calls, emails escalations by their colleagues. They urgently requested information from me 2 weeks ago, which I responded to withing a couple of hours. Its around a payment that needs to be made to an international supplier. The goods are ready to ship, but in two weeks this department has ignored all my call for help. They have my money, but will not assist me in getting it to the recipient. Two weeks of hell and no response from them
