BlackBerry 8520
Display problem

I bought Blackberry 8520 in April, soon i started facing problem in charging the phone, i had to leave the phone with Redingtton service center in Ludhian for over 10 days, i was told it has been rectified and i was issued a new phone.

Soon i started facing Screen display probme, this problem occurs sometimes, at times it flickers, at times it goes blank and sometime works absolutely fine.

i went again to Reddington cetner, i was told it is ok, but in a day i face this problem at least twice and phone doesn show proper display even after switching it off by taking off battery etc.

I am not satisfied with phone, i require immediate replacement, had it not been for blackberry email services i would have dumped this phone long back

if any responsbile one listening or reading, my contact number is 09779942111
