proactiv they dont cancel your account when you ask, and then bill you for packages you never receive, and then send you to a collection agency !!! des moines, Iowa

my wife signed up for proactiv last year.
i saw the charge to our credit card and questioned her what it was. she told me it was for our teenage daughter. there would be 3 chrges of $29 dollars to our credit card and that was it.
after i saw the 3rd charge, i called proavtiv to make sure it was done. they then said there was 1 more charge comeing and then the account was closed. that was in june of 2010. in november of 2010 i received a bill from proactiv stating i owed them an amount of $68 for a package i recieved from them. i spoke to a gentlemean named patrick that showed that i did cancell the account in june, but they sen out another package by mistake. I confirmed we recieved no package. he said he would send a letter stating there was no delivery, and would make sure my account was cancelled.
as i was witing for this lketter to fill out, i recieved another bill from them 30 days later. i called again in january of 2011 and spoke to a eric. he said he sees where i cancelled the account in june and then spoke to patrick, and he would send out this letter to state i recieved no package (as if the burdon was on me to prove i recieved no package rather than them to prove that i did recieve it). i recieved an affidavit from them and filled it out anyway. i sent it back and that was that. then today 7-5-2011, i recieve a letter from a collection agency that i owe the money to them. i called proactiv and spoke to them about how discusted i was, and how negligent they were for this entire mess. a supervisor named mellisa told me one it goes to collections they cant do anything about it. i said what about the affidavit i sent back. melissa saked me "why didnt you follow up about it ?".
WHAT !!!!??????? I recieved nothing else from them !!!! she stated they sent a bill in february, march and april.
I said if that was the case (we recieved no letters), it didnt matter anyway. proactiv was 100% negligent of this whole situation. And i said "if my account wasnt cancelled, how come my credit card was no longer charged?". melissa said "they removed my credit card in september". i said AH HA !!!!, that PROVES you closed my account !!!!. they then said it was my problem., when i informed her she was being recorded, confirming that i cancelled the account and spoke to people several times confirming it, she informed me "you cant record me !!!". i said "this call may be recorded for fraud reasons". she then hung up on me.
