Unhappy

Called Telkom 1021 yesterday after work(21/08/17). Spoke to a lady in billing dept. Explained to her that I was not in the country on payment date and would like to do payment and enquired on outstanding amount. She than advised me that oustanding is R1130. I told her i will be doing payment immediatly and she assured me that all is in order. I proceeded to Shoprite to do payment of R1200. woke up this morning and services suspended(22/08/17). Called again 10210 billing. Explained to them the story. Again no one can assist. I Than requested a manager to call me when free. Was told that its an inbound call centre and managers wont be able to contact me. Im tired of this service. Please assist.
