Consiglio del giorno che ti può essere utile:
For the last 5 years I have been getting Cox 'gigablast' internet for about 40% off the advertised rate because each time my discounted rate expires I call and tell them that I will switch providers unless they continue my promotional rate. I think the last time I did it the first person I spoke with “couldn't” do anything about the price. So I told them I would call back to schedule cancellation after I had scheduled the start of a new service; then when I called back the new rep renewed my discount.
