closure letter

received the worst service ever from two Finchoice employees, Crystal Hendricks and Kevin Louis. requsted a closure letter from Crystal and she advised as soon as payments is made it will be sent but that didn`t happen instead she sent a paid up letter which I dont want. Want a closure letter want nothing to do with this company after the service I received, Kevin Louis is one of the manager`s at the call centre and he doesn`t know customer service at all. instead of assisting me he was telling me he is knocking off after making me hold for 30 minutes, they cant give me the contract i signed stating i cant close acc,ount all I want from this company is a letter stating my account is closed and I want nothing to do with them.
