Ing Bank review: improper treatment of international customers

I am a researcher and do not speak Italian. I have a bank account in Ing bank in Italy. They suddenly blocked my account for no reason, and when I went to the bank the refuse to talk to me. First of all, when I said I can't speak Italian the asked me to leave the office in English. They could speak English it was obvious but they said we do not help you if you do not speak Italian.
Then another person at door told me to call the service centre. I called the service centre in which is totally in Italian. After waiting for 10 minutes, I could reach the operator. But she picked up the phone and I said I have a problem and need to talk to someone in English, she just simply hanged on the phone without saying even a word.
Then I tried to use the online chat with a hope that I could use google translate. However, after talking with chat service with the help of Google translate they told me to call the customer centre.
I am really disappointed about how they consider their international client. I have no idea how to get in touch with the bank to even close my bank account and transfer my money to another bank account.
I am in a hard situation because I do not have access to my account and I do not know what to do.
Please help me through this situation.
