Losing My Channels

Every month or two I need to call tech support because I keep losing the premium channel package that I have been paying for.  It has happened again and I have not been able to receive the channels in the 1100 and above range, i.e., OWN, ID, DIY, Cooking Channel, etc., since Friday.  I have tried to contact tech support several times but end up on hold until the battery runs down on my cell phone.  I am tired of dealing with this problem and so would like to cancel these extra channels since I am not getting what I am paying for and the constant monthly hassle is just not worth it any more
