Matrix Car Tracking fail again

This company is shocking. They just ignore their clients. I sent an email rquesting that a "human"contacted me regarding upgrading the trackers we had in our vehicles. I still haven't received any acknowledgement from '***'. This is a misnomer as they don't care about their customers. I tried their opposition CARTRACK who also didn't reply but at least raised a ticket number. I'm still looking for a company in this field in SA that want to have customers
