Pathethic service

Too much clients, cannot provide proper service. I have a debit order loaded, yet I have to phone monthly to advise them that the money was not taken out of my account. My tracker was not even activated after installation. i had to call, only to be told that it's my responsibility to call them monthly to test the tracker is working. i called three times in connection with my debit order and was cut off all three times after holding on for over half an hour. Now they refuse to cancel my contract
