MATRIX Company is ***** and ******

I have been a client of Matrix having their Beam installed in my car. I have never seen such desperate people as they sent an invoice with an amount of R500. 00 owing for some roadside assistance that I don't know. Phoning them nobody answers the phone sometimes they drop the phone off. Knowing that I am not willing to pay this money they decided to deduct twice or three times from my account without my permission. Yoooo these people are **** and ******. Now they harassing me with messages and phone calls even when I tell them that I have canceled them. I'm warning people not to take MATRIX OR BEAM. Thanks to Capitec I have managed to block them from accessing my account.
