I had the worst experience with them trying to add the new channels.
1st round: I ask to upgrade to Greek Super package. All channels come on except for 605 (Antenna Satellite) which shows up in red on the guide and the message 013 (not subscribed) pops up. Of course I had it until the phone call. I call, they tell me everything looks "fine" on their end, transfer me to tech support. Tech support asks me to take smart card out, loop the power on and off, unplug for 20 mins. Of course they include the questions of "is there any bad weather, did something change since last time you had the channel" so I had to let them know that the only thing that changed was making a phone call to them. Every time they ask me to do these they tell me to wait 15 mins before I call again, even though when they added the other channels and 605 was dropped it was instant. After 5 phone calls, they decide "it is the PVR" so they are sending a new PVR.
2nd round: I call and ask them to put me back to what I had before (MEGA/ERT/ALTER package and ANTENNA ala carte). Low and behold, ANTENNA now works fine, "PVR problems" nonwithstanding. I report this to customer service, someone actually "gets it," but they still can't fix it. As he is about to switch me to tech support again, I request he just leave me with what I had and drop the whole issue.
Now, of course there are gonna be issues with new packages etc. But it would help if the first response of the people handling the calls was not "well, your dish is at fault, the PVR is at fault, you are looking at it funny, everything is fine and dandy here." Also, apparently nobody creates some log on the case, so I had to share my life story with every single phone call.
