AT&T Prepaid Multi-Line Discount Charges
I am currently having a line under the AT&T Multi-Line discount plan ($45/month plan) which is managed by my friend and he pays $161.90 every month for 5 lines. Recently, my friend and I have removed ourselves from the multi-line plan and changed to the individual plan three weeks ago since we are currently abroad and roaming service is not available on AT&T prepaid. However, when the data plan renewed last week, my friend was charged $161.90 despite having only 3 lines in the multi-line discount plan which baffled me.
Any clarification on why he is charged the same amount although there are fewer members in the discount plan and what can he do for the next billing cycle to ensure that the charges will be lesser?
