Legal advisor states we should mail our certified mail return receipt letters re: non-renewal of current 24 month agreement (set to expire near this year's end) to the retailer and also to DISH network. The only address for DISH that I have is DISH Network Corp., 9601 S. Meridian Blvd., Englewood, CO 80112 This is DISH's corporate address. Does anyone have another address to send such letter or am I good sending my letter to corporate address? Thanks in advance.
