Unsatisfactory service

Notified Vox early December 2018 with regards to commencing a contract from 1 January. Due to the holiday season it was agreed that this be deferred to later in January. After several attempts to contact Vox telephonically and via email, Vox eventually made contact with me and informed me that they now required further notice and extended the connection to 1 March 2019. It is now 7 March and still no internet. Vox ignores my emails and when I phone they keep on telling me that they have escalated the matter and brought it to management level etc etc. But nothing is happening and still I don’t know when internet will be operational at my house in Fourways. I run a business from home and this level of service is unacceptable.
