Appalling service from Vodacom

I'm extremely disappointed at vodacom..I signed a contract with vodacom in December 2020 for wifi at my complex and to date my fiber is not installed. I have called their lines *** to get assistance and have not been successful with connection..in January they sent out a tech after I was told their offices are closed till 11 jan and this is after signing their contract..non of this was disclosed to me before I signed by the way..so I waited! The tech came a month later and they found that my fiber was with another service provider and that it wont be a problem. I was then given 100GB to use while I waited which finishes within 2weeks, which is frustrating as we work from home and have online schooling. I called their lines back and i was told they have logged a message with the server and i should have contact soon..i have asked to speak to a manager and still nothing! I'll be working from home in a week and I'm still not connected and I keep getting sent this 100GB. I recently received a billing from them of R947.49 for a contract I never signed and agreed upon..I feel cheated and ****** and the advisor that initially helped me does not know what is happening and keeps saying she will get her manager on it...at this point all I want is someone to call me a solution , I am TIRED of all your excuses!!
