TFS is making my life hell for something straight forward and easy

I am so upset with TFS, I have been trying for months now to get my late father's NATIS documents which we urgently need. I have phoned about 7 times in the last few months, each time they make it sound so easy, just email these documents, which I have done each time and then NOTHING, no reply, no phone call, no NATIS documents. Then when I phoned again, the apparently have never received a mail from me with this request or documents. HOW MANY TIMES DO I NEED TO SEND IT ???????!!!!!!! How on this earth can I just get what I ask for even though I go through the same process every time. my mother and father passed away months apart in the same year, I have LOTS of admin to do because of this, how can a simple thing like this give me so much extra stress ?????? I expect a call from Toyota to sort this out, or I will leave a review every single day as well as on facebook. I have enough to deal with and TFS are making my life hell. The vehicle is paid off, you have received all relevant documents more than 6 times already, courier my father's NATIS documents as asked over and over and over again. my contact number is ***, my email address is ***, please search this email address and see how many mails I have send this year already.
