FEES

I pay my @ Home account on the 20th of every month or around those dates because I get paid on the 20th. Now the problem I have is that in August I didn't make a payment and in September I paid for Aug & Sept. You did charge me interest and all other penalty charges and I didn't have a problem with that. Now I see in the October statement you have charged me all these penalty fees again. Why charge me penalty fees again whereas my account is up to date? can you please reverse these charges for this month as I believe that my account is not in arrears anymore.
