Telephone Call Simulation (Could you please take a look at it?)

I was sleeping when the telephone rang. When I picked it up I had to hold my breath, it was a call from a company that I had applied for a job a month ago.
Me: Who is calling please?
Recruiter: Good morning. I am calling from the X corporation. Could I speak to Ms Garcia please?
Me: Hello this is Ms Garcia, could you tell me what it is regarding?
Recruiter: I am calling in connection with your CV application and I would like to ask you several questions to know if your professional profile fits well with what we are looking for.
Me: Ok I am willing to anwer you all of your questions. that you need. BETTER, ''I am willing to answer any question that you need to ask me''
Recruiter. Ok I am going to put the call through to the head of the R&D department, please hold on. OR ''please stay on the line''
Suddenly, the line went dead due to a bad connection. OR All of a sudden we got cut off due to a bad connection.

Very good, sorry I can not stop writing in blue. When there is a fault with the telephone connection/line. We often say ''it is a bad line'' ''Sorry I can't hear you, its a bad line'' OR ''a bad connection''

Your English is very good, you only have some small mistakes.
