Bad Service - Vodacom Fibre

I started the application process pertaining to my Fibre contract on 27 December 2018 and received my order confirmation letter on the 2nd of January 2019. The letter showed that I will receive a notification that will allow me to book an installation appointment online. I did not yet receive this notification and the numerous interactions with the Fibre contact center also did not help. Call center interactions are escalated for action but to no avail. My attempts to speak to a supervisor or manager was also to no avail. My understanding is that Vodacom's promise is to do the installation between 7-21 days. I hope to get a response from Vodacom on how this matter will be resolved with at least a commitment to do the installation on an agreed date.
