Broker's customer support

Is it possible communicate and solve issues with broker only via e-mail or chat and not via phone?
Do brokers call you?
Are they fast in answering e-mails?
I'm asking this 'cause english is not my first language and i'm much comfortable communicate through email or chat 'cause i have time to compose and search through google translator words i don't understand.
I'm specifically interested in these broker's customer support - oanda, dukascopy, interactivbrokers.

Depends on the broker some call you some don't

interactivebrokers are great on their support tickets in terms of the answers you get, but some time you have to wait for a reply. they have never called me even while I opened the account.

Have not had experience with Duks but time I called Oanda they where helpful.

from dealing with gomarkets they're also great on speed of email reply and help you get on live chat.

depends on the service you want you can always advise to the company you prefer email contact only.

Thanx for answer.
Does anybody know how about Oanda?
