lets say his grand dad is 120years old
lets say his phone line per minute is RM0.20 flat (i dunno how much
there sorry)
1 day = RM288 (24hrs x 60mins)
1 year = RM105,120
10 years = RM1,051,200
100years = RM10,512,000
RM 806,400,000,000,000.01 will take 767,123,876 years to chalk up,
even if his grand dad forget to put the phone back on the hook for
120 years also seems like a big joke.
