I don't know if it helps any, but when I email them, I use the automated form. Also, when asking my question, I PROVIDE them with the information again, like I said: "I understand you are very busy, but I simply need to confirm that the information on my file is as follows: Address, phone number, blah blah blah. I would hate to have our file or your workload help up simply because of a miscommunication with contact information. Thank you so much for your time, kind regards, Mrs. Nini"
And same with the RPRF, just emailed telling them I understand they are incredibly busy, but wanted to ensure the RPRF has been paid and if there is anything outstanding that they currently require from us.
I find that by already telling them what I need to confirm, it gives them an easy way to check my status without having to type out too much themselves.
I hope that helps, and not sure if it will work for everyone.
