Very bad service and unprofessional

I have an account with Edgar’s of which I opened it long time ago while it was under absa finance then Edgar’s moved all clients under RCS finance without informing us then what is sad 2 months ago I paid the whole balance on the account at Alberton edgars the cashier advised me to pay over the balance then we did that I paid extra to my surprise this week I received a call that I have not paid my account I am on arrears I should go to the store where I paid they will assist then today I went to Alberton as I was told by the lady on the call at store they said there is nothing they can do they give me a phone to call the First Lady on the call was rude she doesn’t want me to ask questions when I asked her to speak to her manager she said they don’t have managers I said please give me someone senior of her she said ok the put me on hold me and locked my account I phoned again same time spoke to the Second Lady Nosipho she couldn’t access my account as it was locked by the previous person who was accessing my account then the process of unlocking the Account took long , they didn’t have proper reasons what is the over due amount for and I want them to close the account and provide me with letter of closing the account and remove my details on there data base this is so unprofessional of the call centre staff while they didn’t train the edgars staff to deal with enquiries about the RCS
