My wife's phone had constant call drops and I took it back to the vendor. He thought it was a phone defect since there was only one reception bar showing on face plate. He gave me a replacement phone and sent the original one back to the carrier. I now got a $50 bill from the carrier due to damage beyond economic repair. When I looked into this they told me there was "liquid damage--which could been caused by many sources including perspiration. Well, this phone was less than 3 months old and was never abused. I am protesting the $50 payment (the insurance I have for the phone excludes this liquid damage issue). Has anyone ever successfully protested a bill to a cell phone company?
I've never protested a bill to a cell phone company at all... but from what I understand, there is something small inside each phone that turns colors when it gets wet at all. There is no way to change this back or replace it and therefore they're able to determine if the phone got wet at all (maybe by rain, spilled drink, etc..). So, I would think this is all they would need to prove the liquid damage occurred. Good Luck though!
Ironically, yesterday someone at work told me a similar story regarding their T720. His kept dropping calls and had horrible reception. He and his wife had bought 2 T720s and her's was fine, but his had these problems. He took his in and finally got an exchange for a new 720 with the stipulation that if any "user damage" was discovered he would have to pay. In 2 months he got a $129 charge on his bill for your same reason, "damaged beyond economical repair". His phone was also only 3 months old with NO user damage. He continued to pay his bill less the $129, but in 3 months they cut off his service (Cingular). He went to the corporate retail store to argue his point to no avail (even though other customers in the store actually joined... (continues)
I have talked to the gentleman where I purchased the phone and he has said there is no recourse in protesting the $50 charge for what they call "liquid damage". Also said that the carrier is now charging $275 for damage that is non-reparable to this phone. Take care of those phones.
This may be too late, but Motorola did the same thing to me. I called bullshit on them and sent the phone back again. It came back "crushed circuits". Also not true. Contacted a group they call the Special Action Team and stated that I wanted photographic proof. The phone was returned fixed. Amazing huh. It cost me 4 months w/o a phone.
