I would like to email a Consulate-General in regards to a job application I made sometime ago. I have received an acceptance letter stating they will get back to me with the details regarding the interview. I haven't heard anything yet and would like to email them.
I have written the following letter, but I feel it still sounds very colloquial and may hinder my interview.
The email I would like to write is:
I have received a letter dated on the XXth of [name of month] 2019 from the Embassy of XXXXX for an interview in the Consulate General of XXXXX in late [name of month] 2020 stating that I will be contacted with the details of my interview.
However, I have not been contacted yet and would kindly request the details for the interview.
The bold and italicised sentence, I feel, is far too informal and perhaps a little colloquial.
What would be an appropriate substitution for this sentence, conveying the same meaning?
