OVERDUE ACCOUNT ???

<p>I have been a Teljoy client for the past 6 years and have purchased numerous goods from them. My last item has now expired and I emailed customer care in February informing them that I am taking ownership, since then I have on a weekly basis received threatening calls and emails regarding a overdue account??? They actually called me last week saying they are calling me to sort out my account, I just rep**** I cannot because I dont work for Teljoy. I also paid 6 months in advance by EFT but was still charged because I was not on debit order although they did have a debit order form but could not take off debit order because there was a credit in the account. I really dont know what to do anymore, they are making my life rediculously unpleasant.</p>
