Sanyo Remote

I bought a Sanyo TV in Oct. of 1999. In Jan. of 2000 the remote stopped working completly! I changed the batteries, tried everything to check it out to no avail. I then tried to call the number on the back of the remote, all I got was a answering machine, and then cut off when I tried to leave a message. I called several times trying to leave a message, with the same results. I then found their E- Mail address and I sent them a request to provide information. I have waited now for several days with no reply, whatsoever. I explained in my e- mail that I had checked all that I could think of with negative results and all I expect is a simple reply.
