Supersonic lack of communication or customer service

We had our fiber connection installed by Vumatel on the 24 /02 /21, we called Supersonic the same day and we’re told 1 to 3 days for router delivery .12 days later and still no router ! I have left as of today 5 messages for senior management to contact me to no avail . My brother whom lives next door to me had the installation on the same day as myself with Supersonic and also wants to cancel do to an absolute lack of communication and feedback from this company ! Their sales team is absolutely fantastic , the min you go to the next step ( customer service or technical ) the wheels just come apart !We cancelled MWEB after being a customer for over 10 years for this pathetic company . I will be cancelling my account before it even can be activated due to the lack of service from this company ! My advice to supersonic , use your sales team as a customer service team , you might just land up having satisfied customers !
