thanks guys....i got his number from the CC and as far as i remember i have talked at this number even before some times. but i'll give another try. theres one more problem. they dont quite understand whats the problem. i tell them that the line rate is set incorrectly but they always seem confused...for eg. they say we will check for line noise, for lose joints, or maybe u might have run out of your first 20 gb limit (even if its the 2nd day of the month :O !!) and blah blah...they dont understand my point.so my ques is...what should i EXACTLY tell him in the technical language...something which he understands quickly and precisely.
