Wrong Episode & no CC

So I actually have 2 issues. For some background, I bought season 3 of CSI: Miami. I paid $26.99 for the complete season. (I have bought 2 seasons prior with no issues.)

Here is my 1st issue. I made it up to episode 11 just fine. However, when I played episode 11 I noticed my closed captioning was missing. I turned it off and back on several times, stopped and resumed the episode, paused and played it, restarted the episode. Nothing worked so I gave up and just watched it without cc. I was a bit miffed but it isn't a major issue. It's minor compared to my 2nd issue.

After episode 11 issue, I had no problems with it until I got to episode 16. I recognized the beginning as coming from another episode, episode 5 to be exact. At first I thought maybe I was losing it. So I backed out to check the episode. It said it was episode 16. So I tried it again. It was still playing episode 5. So I backed out again. I tried resuming, I tried restarting the episode, I tried backing out of the on demand. It was still episode 5. I even fast forwarded to see if it would correct itself. Nope. So I tried episode 5 to see if they were switched. Nope, episode 5 was episode 5. But episode 16 was also episode 5. The title, episode number, episode thumbnail, description was all for episode 16. But the video was undoubtedly episode 5. I contacted xfinity through their live agent chat app. I chatted with a guy forever who swore he would fix it and to give him 30-45 minutes. I did. Aside from trying to sell me their cell service, which I tried on multiple occasions to explain why I can't get it, eventually nothing got done and it still resumed playing the wrong episode. So he eventually transferred me to another guy who was supposed to work in billing to fix it. I reexplained the situation. He sent a reset. I waited. I checked it. Still the same. Then he said there was people designed to specifically handle this situation and he transferred me to yet another guy. I not only reexplained it but I had to explain it in multiple ways to this guy before he understood. Finally he said he understood. I had to check all the TVs to see if they all did it. They did. Then he said he was going to refund it and for me to rebuy it. But he never refunded it and told me to unplug everything first. I did. Still the same. But then I had people waiting on me and had already fooled with this for hours and gave up. I did not get a refund to rebuy it. The episodes are still there so I can't rebuy them as I still own them. And episode 16 is still playing episode 5. I am very upset. I paid for a full season and now have to stop midway through because I don't have the right episode?

I have seen a few people who posted similar questions last year but all those have been closed. Has anybody ever gotten an issue like this fixed? How? Is there a way I can fix it? If you got it fixed,how long did it take? I just need help with this.
