Frustrating experience

What a terrible experience I’ve had with Matrix, they’ve really made a simple request so complex.

Backstory, I’ve traded-in my car for an upgrade and the first thing I had to do was to notify them and we agreed to keep the same contract but get a new device installed which was going to be R800 and we were aligned, however that was never done even tried sending emails and endured their ridiculous hold times which could be over 30 minutes at a time, sometimes they just drop after picking up if they manage to try and help they’ll always transfer to a number that cuts. To be quite honest nobody has the time to put up with this level of incompetence but you think it has to be done.

They haven’t rep**** to the cancellation requests I've sent, even after following up on their *** mailbox.

I’m now dealing with a situation where they couldn’t help me until I had to get a better responsive option but now they won’t stop debiting my account for a car that hasn’t been in my possession from last Dec.Really Frustrating!
