Utterly Unprofessional, and Zero customer service

Utterly pathetic and unprofessional service. May16th I canceled my account. May 17th I recieved confirmation email. End May I get debited. I called again to confirm o canceled my account and to stop debating me. Today an extremely rude woman calls to say my account is in arrears. I explained that I have already canceled my account to which she rep**** "well if that was true, I wouldn't be calling you" I said well thats your I ternary issue because I already have a cancelation confirmation email. She says no I dint so I must email cancelations. I said I won't email again and I have done this twice already so she rep**** " then we will just keep calling you" and put the phone down on me. So I decide to email cancelations to express my displeasure at their lack of professionalism only to have the ability bounce back stating my email was blocked due to being on the blocked list. So she tells me to email and then blocks my emails? Pathetic internal dialogue between departments and zero professionalism . Do NOT recommend
