Telkom Invoices Billing Dispute

The service i keep receiving from the Call centres is **********, I called early August 2019 to ask for my 2 Telkom Invoices to be Split for July and I was told its too late the Invoices cannot be separated but can only be done for the August Invoice ( A Manager / Supervisor named Katlego), my August invoice is back now and its not Split, I called the Call centre again Friday the 6th Sept and “Thato” assisted me and said they will call me the same day with Feedback , I however requested a case number so that I can follow up also, Saturday the 7th an sms comes in saying “case is resolved”, Monday morning the 9th I follow up Again on why my case is resolved and yet I don’t have Split invoices and no call-back as promised. I am told The Changes have been made for the September month meaning I cannot claim AGAIN, its Intolerable !! This call centres continue to be Useless I need my Invoices split so that I can claim at work for both Data and Mobile contract separately. As a customer I cannot be held liable for mistakes that Telkom employees continue to made for another month while I have followed their “so called procedures’’. I have had enough of this very poor service.
