Phone calls

I pay my monthly installment (and more) before the due date. Every month on my statement there is a written note at the bottom stating I am in arrears. To top this, I then get phone calls on a monthly basis any time from the 25th harassing me asking when will I make payment. I explain to the call centre operator I am not in arrears and there is still time to make payment, why is she asking me. I will NEVER purchase from Homechoice again, most unprofessional service ever! I cannot wait to see the end of this account. Harassment in all forms, phonecalls trying to sell me things on a monthly basis and phone calls asking for payment for an account which is not in arrears. Please can you just stop phoning me? Allow me to pay my account off and then please close my account!
