Translation of inexcusable in Spanish

One of the users claimed that the speed of the website on facebook was very slow. Did you experience the same issue? Yes, I've also noticed that the site is a little slow, but not so slow as to find it necessary to advise you.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
I apologize that I have not written for such a long time! Please call me on my new phone number, that would be great! How is your son feeling, has he been recovering? I am sure that he will be fine.
