NO INVOICE AVAILABLE

Within this last month I must have phoned Vodacom's call centre more that 7 times to request a copy of my latest invoice. Each time the call centre agent will send me an e-mail but with no invoice attached and then I have to phone the call centre again and explain to them again, that no invoice was attached to the e-mail. The call centre agents have escalated this matter twice already to I don't who, because apparently no team manager in the call centre can talk to me and assist me with the fact that there is a system error. I have to claim my cellphone accounts back from my work every month, and besides from requesting this from Vodacom from the inception of my contract, not once have they been able to in this day and age of technology, to just e-mail me my invoice on a monthly basis. I have to phone in every month and request this. I can not wait for my contract to expire in June so that I can move to another network. This is really ridiculous
