I am applying for being the advertiser on CJ. A regional sales manager replied me via emails. After several emails, she wants to call me. I am a little nervous, because i do not know what they will ask and my oral english is not so good.
You could try to tell them that your spoken English is not very good and that you are afraid that you wouldn't understand them - tell her that because of this you would prefer to sort your issue via emails. Or if you have a fried who speaks English fluently, you could ask him for help with the call.
