Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Other bank product/service Making/receiving payments, sending money

On - - I made an on demand transfer from my PrePaid Citi US account to my - Citibank currenty account for the amount of $2500.00. The money never reachd its destination. This transfer had been performed on many other occassions over the last 3 years with no problems, however this time the money is missing in cyberspace and I find the reaction of Citibank, or - who appear to be doing the investigation as unsatisfactory. It has almost been 2 months that my money is missing, they have acknowledged that the transfer money was taken out of my account and say that this is being investigated but this is really not good enough as I am suffering as a result. This money should be returned to my account and they can deal with their administrative mistake afterwards. This has put me in a very tight financial situation and has left me without being able to pay my bills - I have since received charges from the bank from unpaid direct debits and have had to ask for an overdraft - this is very stressful and upsetting and through no fault of my own.
