Cingular Wireless dishonest Forth Worth Texas

I am a cingular customer for almost 2 years. I have upgrade my phone after 1 year of service on January 2005 and I purchased Sony Ericcson Z500a, for $79.

When I received the phone was working fine but after 1 week the speaker phone I couldnt hear the callers voice. So I called Cingular to fix the problem or perhaps refund, but all I got was transfer from customer service to the sales dept for over 3 hours with no result. So I did it the same thing on the next day and still being transfered for over 2 hours without result, and they finally told me that i can exhange it with the refurb phone or purchase a new phone with the original price which was $199+ tax.

So I decided to purchased a new phone Z500a which arrived a week after, the phone is working well but its not worth the price though.

The refund policy is so confusing. I would get refund if I had a phone for 30 days and wont be refund if its less than 30 days?

So after a month I call the cingular to ask where can I return my new broken phone, and they told me that I can send it to return dept which I did send it with certified mail, and it would take 90 days for the phone to get fixed or refunded. Somehow I lost the receipt from the post office, and I've been wait and wait till now approx 8 months, I never get my phone back, and I cant claim the phone because I lost a receipt.

My question is where IS my phone now? I think that they received my phone because I sent it with certified mail and someone had signed it, but probably they fixed it and resale it again as (refurb) phone as I saw at the www.cingular.com, but I may wrong, who knows.

I really hope that Cingular staff read my complain and realize that I am a good customer and voluntarily return my phone so I can fix it and give it to my brother otherwise Cingular can keep it and resale them again. Thank you Cingular for BEING dishonest I just wish that I could cancel my contract right away.
