****** disguised as good guys

The guys haven't finished installing everything, the alarm (the remotes, the app, the siren, basically everything) is malfunctioning and we've told them several times and asked them to come finish installing what we have paid for and is rightfully ours. They keep saying that they'll send the technical team but its been almost 2 months. The sales agent has blocked my number so I can't even contact him. Meanwhile the damn thing keeps going off in the middle of the night and a response officer has to keep coming to check if everything is okay. I'm about ready to take them to the ombudsman and consumer commission for failing to deliver the products and services that we have and are paying for.
