Billed Incorrectly

Billed Incorrectly !!!!<br> Just spoke too the call centre ( ***) The most *********** people working there .Firstly I was finding out why I had too do a double payment on my Edgars account in Feb. Instalment due R214.73 and amount overdue R213.73 . So I asked where I got behind the first lady at the call centre said in Dec .Then I asked too speak too the manager who said I got behind with my payment in Jan then corrected herself and said November .Which both was paid every month which is confirmed on my bank statements . Then got very upset and asked again where did I get behind no answer . Asked her did I Pay in November ( Yes ) did I Pay in Dec (Yes ) did I Pay in Jan ( Yes ) did I Pay in Feb ( Yes ) . So where did I fall behind on my payment ? I want a apology letter and explanation regarding this incorrect billing on my Edgars account .After that I will pay off the amount due and close this account .
