Extremely Poor Services - Vodacom Viber

I made an application in December 2020 for Viber to be installed in my house. My application was accepted and in January 2021 received an LTE router until the fiber is life in my area. More than a month ago a company came to install a small box inside my house and until now I am still using the LTE. My biggest frustration is the failure of VODACOM agents to give me clear indications as to where the problem is and when will it be solved. For months now I am in the dark. I send an e-mail that I want to cancel all my connections with Vodacom. Instead, I received in one day two Vodacom agents asking me if I am interested in Viber offered by Vodacom. Just yesterday I spoke to a guy called Max who promised to contact me between 16H00 and 16H30. To date, I haven't received any communication from him. This is the worst service from a telecommunications company I ever experienced. Your service ethics and professionalism is extremely poor, Vodacom.
