Deagostini wont send my build your own Mclaren issues

I have been having endless problems with getting my “build your own McLaren” the MP4-23. I have been busy with this project for about 6 years now and the reason it took so long was for the post office strike which took about 2 years to get back on track and also for me having to relocate a few time around the country (job requirements) however the biggest problem is that I can’t get any tangible response from Deagostini in the UK who send the issues to Jacklin enterprises in Pretoria. I am only 2 issues away from completing this mammoth build and only need 2 more issues namely 73 and 76. This is out of 85 issues. I have received issue 73 twice from them as there were mistakes in the parts package, this being one part that is actually from the issue 74. Issue 73 and 74 are mirror opposites and therefor one of the wrong parts in the issue 73 can’t be used, and I cannot finish the build until I get the correct part. A keep getting an automated response from my emails to them saying I can view my account online. I have spent over ZAR 8200 on this build only to be 2 issues short. I don’t know how to make things simpler for them as I have even sent them photos of what they sent and what I needed. But the last mail I got from them was “am I sure I have the correct issue number”
