Certificate of residence question

I recently sent a request for a certificate of residence through the "e-mail a form" option on HMRC's website and made a mistake in one of the fields, I wrote that I ceased to be a resident by a certain date where I should have written that I am a tax resident until the end of the tax year, but I ceased to physically reside in the UK by that date. Is there anywhere I can write an e-mail to with my case number to correct that error?

Hi
No.  
You will need to submit a new request for a certificate of residence, with the correction applied.
