Still waiting for a response

Last week I called in to the call centre to ask for a quote on a contract. I was almost immediately contacted back with all the information I required. I was contacted twice after that, to ask if I was ready to do the installation. Both times I mentioned that I would let them know as soon as I had made the decision between continuing my contract with Tracker, or moving to Netstar. the contact person at Netstar asked me to respond to his email when I had decided, and he will get the installation scheduled etc. On Saturday, I responded to his mail and asked him to contact me to schedule installation. I am still waiting- its now Wednesday. I shudder to think what the response time would be should something actually happen to my vehicle, if the response time to a sale is this shoddy. I guess I'm calling Tracker to un-cancel my subscription and get a new unit installed.
