No Pay No Service

Morning, I'm not very happy with the service I have received from Teljoy. At one stage I was paying way in advance. Yes I acknowledge I have fallen behind on my account as everyone has fallen on hard times. However I have an appliance that I cannot use and Teljoy won't send someone out until the account has been paid in full. Why do companies only look at the now and not at your history. I had such a battle with them to swap my old washing machine to the new one and had continued issues with people not coming back to me. Only once I had escalated my enquiry was something done. I think its time consumers had another option besides Teljoy to consider.
