Fed up!

My Edgars accout gas been handed over to this company. They oganised a settle balance for me. I paid this settlement balance in full in July. They said as soon as the amount is paid they will let Edcon know,my account will be settled and I will be able to use my account again. This has not been done. I phoned them in September again. Their responce was that they will take me off their books because they dont know why my account is still reflecting on their system. Today 14/10/15 they have still not reinstared my account. They are very fast to phone everyday if you owe them, but when you pay, they are very slow to reinstate.
