ok so I have a question and i need answers asap please!

ok so Ive been calling this guy for about a month that I know, and the minutes are mobile to mobile so its the price isnt going up it remains the same.

My question is, how can i get rid of the log that comes in the paper bill? meaning I just want it to show the minutes i used and the over all price.

I dont want it to show the incoming and outgoing numbers.
PLEASEEE if anyone knows tell me asap.please. I'd appreciate it.
