Bad customer service

Hi I have been edgars customer more than 20 years the service that we are getting since is no longer under adcon is pathetic.. I am getting call from them almost everyday saying that I am owing which I don't. I have never bought at edgars more than 500 since I have been with them and there was never a time that I don't pay. on Jan I went to maponya and paid R100 on Feb I ask them my balance they said is R800 I went to customer service they made a call saying I am VIP Insurance and funeral cover. I said to the I don't know anything about they said they are going to investigate which they did and said they will -R452 and I can only see that month end of march. I wnt to trade route last week and spoke to them about the VIP Insurance which they said they are going to investigate but I am getting call everyday. they are guys inside their store who said to they update you contact and email all to find that they register for insurance. if you can go to edgars customer service you will hear sad story about that store. I don't need anything to do with Edgars anymore. I need them to tell me my balance and close it sick and tired is the terrible service since edcon left them. I wish this issue can go so far to their CEO and see how are they going to loose customer because of bad service.
