How to contact Corporate and get help

I have had trouble with my Satellite P205D-S7438 since I bought it. Tech support knew nothing but reinstall, which I did unwillingly four or five times. Customer Relations pleasant but can't give me a new one.

Cust. Rel. got me a third tier tech rep who didn't know what to do about a Toshiba utility that didn't work. I finally figured it out myself. Hate to go into the registry, I am no technician. But I found one key with that name, backed it up, deleted it and reinstalled.

After SP1's free advice from MS, so they no longer said I had to talk to the manufacturer (who'd refer me to MS or so MS hadn't told them anything about that) a tech kept telling me to do a repair upgrade. I explained with Toshiba's repair disk it isn't possible. She sent me a free disk! I reformatted and reinstalled and was able to talk to MS directly. Got upgraded to a higher level of support there. I had so many event viewer errors it was unbelievable. He finally had me partition and install there. It had the same errors from the beginning. I did a lot of Googling and found out that all the kernel-WPEA hardare checks I was getting were related to hardware problems. And AMD has a utility to put them into English. Good thing I found it as I was then getting FATAL machine checks. The AMD MCAT utility indicated both cores were corrupted by errors, there were errors in the L2 cache, bunch of other places.

First time I sent it to their repair depot, it came back as just being a bad Vista install and they reimaged, despite my four-page memo explaining about the machine checks and with pictures of what the MCAT reported. They also didn't return my SD card. When I called they said they'd get a RMD from corporate to replace it. Next time I called, when they had it back again, with another four-page memo, they said they had returned it. Customer Relations said they had talked to the depot but was told it had been returned and corporate said I had to talk to the depot.

When I got it back the second time saying they'd replaced the cpu, I STILL had fatal machine checks and so it went to corporate engineers with another memo, plus the prior memos, although it was a few days past the warranty. I was told it would take much longer to get back, they would tear it apart and really go over it. Unfortunately, afther the SD card problem, I was afraid to send my 2 GB RAM I'd bought and put theirs back in. I didn't reseat it well, got it back really fast saying that was the only problem, all tests were passed, he'd played a movie. There were fatal machine checks while it was there! I'd even put a copy of how to use the MCAT in a prominent folder on the desktop, with another folder of the pictures I'd taken. He can't have ran the MCAT or looked in Event Viewer. And when I got it back, Vista didn't recognize the DVD so don't know how he played a movie. Customer Relations says can't send it back to them again, it is past warranty, there's a number I can call on the website to talk to someone at corporate. A general number! Who do I ask for?

So, has anyone had any luck getting someone at corporate who will be helpful and what is their name and phone number/email? Only thing else I can think of is to report them to the Better Business Bureau or else to Ohio Attorney General.

Advice, help, Please!!!!!
