Rogers Ignite TV

I was talked into Ignite by a Rogers sales person because they would give it to me for less money per month than my regular cable. I have had 4 technicians including the first installer come to try to fix it and NO ONE can fix it! So I've wasted 4 days coming home from work to let the technicians in and they still can't fix it! On 2 of the 4 TVs, the sound gradually falls more and more behind the picture so the picture and audio are totally out of synch! It looks like I'm watching a poorly dubbed movie! It's SO irritating! Since installation, they've sent 3 technicians including a "senior" technician and none of them know how to fix it. I was promised that if the senior technician couldn't fix it, they would switch me back to regular cable TV and now they are REFUSING to do that! The 2 TVs where it's not functioning properly are virtually new and they're blaming my TV! Why are they rolling this out when they haven't got the bugs worked out! They refuse to do anything about it after being promised that I could switch back to regular cable if they couldn't fix it. Now I've got perfectly good cable boxes that I purchased years ago that I can't even use anymore! What a sham!
