anyone experienced this before??I got connection in sep 9... in the bill my rent and usage was calculated from 09/09 to 30/09..no of days: 22total no of days: 30ratio : 22/30=0.733333333so my rent = 250*0.73333 = 183.333usage allowed = 409.6*0.7333 = 301(similarly calculate for ur first month)Initially what i thought was though we get connection in the middle we might pay rent 250 and allowed free usage is 0.4Gb.. so i tried to ultilize up to 400mb but this ratio factor was taken to calculate the rent and usage allowed.. as a result i paid extra amt for usage beyond 301.. (although rent was for used period only but usage allowed???)though i am under plan 250 amt was less but think if ur plan 500 or more..so new users for the first month wake up..
