Samsung Mobile, Model - E2120 — logo getting hanged frequently

Address:

Kutch, Gujarat

i bought a samsung E2120 last year in the month of june. since then it is about the 4th time that the logo of my mobile is getting hanged. each time i get it repaired from the customer care, and then when i insert the sim, there is no network, and it gets hanged again in a few time. the man in the service centre says it is the problem with the hardware.
some even adviced me not to use samsung.
i did like to get my handset replaced or the money back, cause even one year has not completed since i bought this handset, because this frequent hanging of mobile has already created a lot of problems.
