Misleading sales

My January debit order failed and decided to leave the wifi suspended and pay again 1 Feb for coverage for the month of Feb. I received messages stating that I could pay my premium which is R399 and be covered for 30 days. I contacted webafrica on 26 Jan and they confirmed if I paid I would be covered and the next debit order would be due 1 March. Today I received a message stating I owe and will be suspended.Upon querying I was told I need to pay the pro-rata amount to avoid disconnection. I advised the agent how this came about and even if there is pro-rata (which I was not aware of) I would need to forster be covered for the 30 days I paid for. I cannot be suspended on the 30 days I paid for due to pro-rata I was not informed about in the first place. This seems very sly to me and I feel as though I was **** to in the first place just to reconnect with a catch. The agent advised that it is vumatel that works this way and not webafrica.
