Getting the runaround!

I don't know where to officially complain about the poor customer service I'm receiving but I'll do it here. We decided to upgrade our service and add TV. We called Monday and was told to pick up the receiver on Tuesday and someone would come out Tuesday to do an outside install. No one had to be home and would be quick to do and after, we could do the rest ourselves with self-install kit. So I go Tuesday to pick up the kit and I'm told the install can't happen until Friday. What happened to Tuesday?! The guy said no one could come that day and he wasn't sure why we were told that to begin with. So whatever. We're now scheduled for Friday. Then we get an email saying install wouldn't be until Sunday. What the heck is wrong with these people?! Then on Thursday a tech shows up knocking on the door (had no idea he was even coming). Then he leaves. A lady at the Cox office calls and says the tech showed up for our scheduled install but no one was home. I told the lady, "First off, no one ever told us anyone was coming on Thursday. It was supposed. To be Friday. And also we were told no one had to be here since it was an outside install." So she then says someone will be here Sunday then. I explained we were told FRIDAY!! We wouldn't be home on Sunday anyway. She then says someone would come out Friday then. I told my husband all of this so he calls the office and is told this is 100% the techs fault. It clearly says on his work order this is an outside install. They would be sending him back out that day (Thursday) and get this all taken care off. Well, he never shows up. Friday morning (today) my husband calls and he gets told they're too booked up to send someone out today but someone could come 'sometime saturday'. First of all, our original install date was Friday and now you're telling me we can't even be seen?! You're too busy to come flip a dang switch?! My husband called back and someone said they would try to contact patient advocacy and get his moved up to today but really, this had been RIDICULOUS!! When we had Dish they came out and did the whole home install THE NEXT DAY! When we moved the Dish guy showed up as we were moving in and installed our new dish THAT DAY! But apparently Cox can't even send someone out here to take maybe 10 minutes to take the filter off the box outside real quick. We do the rest of the install ourselves. We've been getting the run-around for days! You better believe if someone doesn't come out TODAY (our original install date anyway) then we are taking this stupid box back and going with another provider. Never in my life have I experienced such unprofessionalism......
