Hi, I admittingly haven't read this whole thread but I did skim it. A couple things of note.
1. Don't email them every day on the same issue.
a. This should be obvious but not only will it not speed up your service, it slows their CS down further for everyone else.
2. Email the specific department.
a. This will cut some time. If you are only emailing email@example.com
when you have a security issue or an issue with the (store, as above) you should just email that department directly.
3. Show some patience, FTP will get it right.
a. I've been a regular at their site for some time now and they are reasonable and fair in all the dealing I've had with them. They will right the wrong. Yes, their CS can be crap, but I'm gonna honestly tell you a trick that worked for me pre-black card: Treat them as people. Be polite, make a non business related comment to open your email (hope you are well after what I'm sure was a busy weekend!) something like that. CS reps are people too and they'll just be more apt to go even further and WANT to help you. I know that's not how it should be, but it is and it's like this in almost any CS related field.
4. Become a black card member
a. lol, I know this is easier said then done but as a BC member I have to say...it's truly awesome. You get replies within the hour.
