Owners/service Manual problems of the 2002 Toyota Tacoma

I purchased the Tacoma 10/9/2013, I noticed some of the recall repairs had not been made by the previous owner, I took it to the dealer, 10/29/2013 for the necessary repairs. I was informed by the service guy, using a hammer, that my frame was crumbling and I would be needing a new frame as well. I called Toyota customer service numerous times and all I ever got was, I'm sorry, and how they were well aware of the corrosion problem with the frame on the 2002. The rust problem on my Tacoma is so severe, the truck is starting to buckle, no space between the cab and the bed at the top. It is in such bad shape no one will put it on a lift! it will be the complete and single cause for the demise of my truck, and quite possibly myself. I had just bought the truck. I will be driving the Tacoma when the frame breaks apart and I will probably die. 9/11/17 I wrote james letz, ceo of Toyota, and manager of Toyota motor engineering and manufacturing, I stated, "I followed the corrosion prevention in the owner's manual. The quality of the frame on the 2002 Toyota Tacoma is inferior due to inadequate rust protection at the factory. " 9/28/17 I received a response by phone from grand prairie, TX. He told me there was a recall letter sent out to the owners of 2002 Tacomas, informing the owners to check for rusting and corrosion on the frame, and they could bring the truck in for a rust prevention spray; however, it expired 2011. They obviously know how severe the problem is. I told him I was scared, and he answered, "I understand I would be too. " he led me to think nothing was going to be done, but it was up to the engineering and manufacturing department, oddly enough, that is mr. Letz!.
