Waiting 2 months and multiple calls to try relocate a fibre line - no progress

We have been struggling since mid March to relocate our vodacom line as we moved premises. We have completed forms and submitted the relevant paperwork. Everytime we call back to understand progress,we get told that a technician will contact us to make an appointment to relocate the line. It is now mid May, 2 months later and our multiple calls have been closed without our line being relocated. We keep getting told that we have not responded to emails, after changing our email address with Vodacom multiple times, they still send the emails to the incorrect address. They then dont get a response and close the call. VERY frustrating and poor service.
