Very Disappointed

I am very disappointed in their bad service and lack if care for me as a customer. I have been with them for about 30 years with many vehicles, which does not matter at all to them. I have to resort to hello Peter, as they do not assist me, once again showing their lack of care. I have been paying for a device for 12 month that has not been working (tied in with a payment for 2 other vehicles). I have reported it, and asked them to refund the payment, and still today they keep charging me, and thus after about 10 intense phone calls, which I get promises and no action. I am very disappointed with this company. Am looking to move all.my vehicles away permanently to another company.
