Dear K.Anfry,
Firstly, I have to apologies for my late replying and thank you so much for interesting in my email.
According to your recent email that you are going to call me on 4th October,
I am afraid that I might not able to understand you due to my very poor listening and speaking skill of English.
Well, but I can write and read English with no problems.
I am willing and do interest in working for your company.
