Unaware that Samsung Captivate was "Discontinuing". AT&T used it as an "UPGRADE"

I have spent many days and hours with AT&T Customer Service and with Techs as well.  I have email my concerns so that they would have a written complaint.  I have contacted them several times.  I received an email which in the beginning implied that I had past the 30 day "Buyer's Remorse" period.  With all that has taken place I have begun to have "remorse" in choosing to renew our 3 contracts.  I was not aware that the phone was being discontinued when I started having problems. I began purchasing accessories for my phone because I did like my phone. I have had consistent problems with my phone notifications in "texts received", "voice mails", and missed phone calls. My major uses of a cell phone is TEXTING and being able
to receive and make calls and being notified.  I have had techs make sure that I have all the updates. They have done a diagnosis over the phone and still my phone does not notify me. I has become hard to consistently keep my phone by myside to check to see if I have missed texts or calls.  The icons were not appearing as well in the status bar. Now my phone has begun to freeze. We've been with AT&T for over 10 yrs. We've never returned a phone.  I became quite concerned that a "discontinued" phone would be offer as an "UPGRADE".  I've been through numerous techs and now have requested that maybe I should speak with someone who is over sales and marketing.  I was willing to "reset" my phone because I wanted to keep it and overlook the other thing such as APPS, games, etc. that I could do without.  I just wanted a phone that would do at least the basics.  I trust that AT&T will eventually fix this. I was sent many "links" to read of which I was already aware of; from taking the batttery out and the likes.  I remembered reading before I purchased my phone that if something goes wrong after the 30 days of trial time then in sending the phone back, should it some reason "work" for AT&T then I would have to pay full price $600. for a discontinued phone.  They also suggest that if I liked the "Cappy" so much that I
go and purchase it somewhere else for the $600. I have been extremely disappointed.  I recognize that customers are "ranked" and it made me nervous to send my phone back and end up with nothing.  So I am trying to decide what to do.  I did receive an email for a person stating that he would have the matter resolved by the end of the week and was somewhat helpful, though, I do no know what to expect.  I just didn't want anyone else to have to go through all that I have.  My phone has begun to freeze at times and I don't use GPS or email. I can only imagine what would happen if I attempted. Please do your reseach and check forums, etc. and then do some more. I depend on shoppin online and I do read comments by others who have the products from clothes to gifts for my family. I make it a habit of commenting on things that I buy to help others who are unable to shop. If this saves one person from anguish then I'm glad that I took the time to do this.
Sincerest Regards to Happy shopping!!!
