Samsung Galaxy S I9003 — Fed up of samsung service center

Address:

Delhi

dear sir,
i had given my samsung galaxy s i9003 for service on 31.10.2011 due to software problem,on reaching the service station they asked if there is any other problem,i told them a button i felt was lagging but i told them it mostly will be due to software, inspite of that they opened the phone in front of me like an amateur(they dint no how to open the phone at all,they were passing it to one another),he then tried closing the phone which was again difficult for the people..he showed me the phone,it felt pathetic the lock key was smashed in and there was then network problem in it..i gave a perfect phone hardware wise to them,which was all damaged by them,the next day i was told by samsung people there is a motherboard problem in it..i was shocked!!!it was all perfect while i gave them..i called up the samsung care after explaining the whole issue i got a call from the service people there is no fault in the motherboard or the lock key...after seeing how much knowledge they have about there product i claimed i will not accept this set .and demanded for a replacement but i got a very lame and bad response from the service station people..i am fed up with these people`s behavior.nil in technology level and they are into servicing phones.
