Sending my invoices that I have not been receiving

I have been battling to get my invoices and itemised billing (which I pay for) Have tried the call centre many times which is a real laborious process and have to go through the process month after month. I previously received them according to their e-billing process. Eventually I made contact with Amo Ngobeni and her assistance was of an excellent nature. She was patient and waited for me to open my laptop. She sent all the outstanding invoices to me discussed some of the content that I did not understand. She has organised that these invoices are sent to me timeously on the date when they are due going forward. Thank you Amo you are a super *****
