Poor Customer service

I had arrangements with Altech Netstar to get a tracking device fitted in my car. The time that was specified for the fitment to be done passed without getting any communication from the technician for the delay. I called the customer service center but i was made to hold whilst they try to get a hold of the technician (I was made to hold for more than 10 minutes), they were unsuccessful in getting a hold of the technician and told me they will get back to me. Its been 4 days and I still don't have the tracker fitted in my car.
