Tracker never assist with faulty device

You just keep your clients in the darkness of all uncer*****y. I had a prefitted tracker in my new wheels and upon activation it was determined faulty by you. Called to arrange for technical support and it's been long enough and no one even bother to call and confirm when such technician will be coming. I've been phoning on a daily base and whoever responded kept me holding till line drop.

I had a planned overseas travel and it's illogical to keep paying for something faulty let alone the risk of having nonfunctional tracker.

Can anyone assist.

Worst way to retain a client.
