angry?

if you keep calling someone on his/her mobile
but you keep hearing "the m1 subscriber is not getting a response...blah blah"
will you get angry?
it goes on for about half an hour...
then finally the person manage to receive your sms and call you
and the reason the person gave for not able to receive your calls
is due to the poor reception in his office
especially in his server room...
will you still be angry?
however the person keep insisting that it is not his fault
as he is not aware of the poor reception...
will you continue to be angry with him?
:(
