t mobile usa t mo T Mobile need to resolve this matter ASAP bellevue, Washington

when my new g2 just went blank for no reason.due to the warrenty t mobile sent me a replacement htc G2 during January. and once i recieve the phone i sent back the phone in the box with the returning ups label to the TMOBILE National return center. i just give to the ups guy who picked up all the shippment for my work everyday durin the week of january 17th. 2011. (i have sent out many ups package this way it never has any problems all thie year)
Around end of January. i called to follow up my return old handset.since i knew that if they dont receive it within certain time i would get charge for a restocking fee and the customer representative told me that it doesnt take that fast for them to recieve it right away. and told me dont worry about it.

During Febuary 2011.i got the reminder text msg from tmobile about returning handset. so i called customer service again. and they asked me when i sent it back? and they told me since they are moving warehouse. it might take longer than usual. the following weeks i got more reminder text msg.so i started getting worry. so i called again. and they told me just in case,they gonna file a research investigatione paper, to find out what happened and they will get back to me. however by the end of febuary i didnt get any call back or text msg from tmobile anymore. so i assume tmoble have resolve this issue and they have receieved the return handset

On March 17th 2011. when i check my tmobiles account i have found out that they charged me almost $500 of restocking fee. and i have called them multiple time these couple days regarding this issue. since i thought they have already receive the handset. so i have threw away the return tracking number. and due to that they can not find the unit and only it only shows that the wearhouse still havnt recieve it yet for 60 days.

and i also have found out that they did not submit a research investigate paper that they said they were going to during Febuary. since all research require a return tracking number which they dont have and they did not ask me. they only communicate with the wearhouse to see if they have it. and no claim was involve. and i have also called ups couple times they can not help me without tracking number since tmoble doesnt have any reference number for shippment either. however UPS told me they have to have the return tracking number since all shipper who work with ups should have a record of the label printout.

im feeling that T mobile knew that i have sent out the handset.i have followed every steps and things that i suppose to do.however they do not offer any sincere help to solve this issue. i think its unfair and its not my reponsibility to pay for the mistake and errors that they made.
