A very bad customer experience and onboarding process

I would like to know how long does it take Netstar to send someone for an installation after completing an application. I did the application for the tracking unit on the 2nd of March 2022 and the account was active on that day. I was promised that the technician will come for the installation, today is the 8th and I've never recieved any phone call, I've made several follow-ups still nothing. Today I have now confirmed that Netstar does not care about customers. I wonder if they're able to respond to an emergency when they're failing onboarding customers.
