Reps would not take no for an answer

The Xfinity chat bot told me to call 1-800-934-6489 for the status of a refund i was waiting on. When I called the only options I was given was for new service or other. When the rep picked up, I let them know want to check on the status of my refund and they proceeded to try and sell me some kind of protection plan, I politely said no. They asked again, I firmly said no, I was not interested. They kept going trying to sell me this protection plan. For a 3rd time, I informed them that I had said no 3 times and consent was very important to me and to not ask me again about this protection plan. For a 4th time they tried to sell me the protection plan. I hung up.
 
I called back, a new person asked what I needed. I let them know I was looking for the status of my refund. They tried to sell me the protection plan. I stopped them mid-sentence, and firmly told them I was not interested in any projection plan. I simply wanted to know that status of my refund. They kept going with their sells tactics. I told them again I was not interested, to respect my "no" answer, that I wasn't trying to be hostile and to move on. Sadly, they continued to try to sell me this protection plan. After repeatedly saying no, this was distressing. They kept going; I got anger. I asked if they were an actual person or a robot as each time I told them no they just kept taking over me. They replied they were human and kept going. I told them to stop, they did not. I asked if they were <Edited: Language> insane, as i mentioned at this time anger as my right to refuse was not be honored by your companies representative. I do realize that no matter how anger I was, I should not have sworn at them, and take responsiblity for my actions there. By the 5th time I said no and was ignored I hung up. 

I called back a 3rd time, a new person answered. I let them know I simply wanted to check on the status of my refund and to please not try to sell me something as they were the 3rd rep I had spoken too as I'd had to hang up on the last two as the did no respect my wishes. She basically told me that she would not either. I'd say no and she would continue to try and sell me the protection plan no matter what I said. I asked how this was possible as I just had a refund status questions. She said well you called the Solutions team. I thanked her for her honesty and I hung up. 

Luckily, I found an old phone number for your company on my phone and was able to resolve the issue with an extremely helpful and polite rep. 

As a 22 year customer of your company I expected more from your representatives, especially as this was my last interaction. I moved and your services are not available in my area.

I have the names, ID/Badge #, and times I called. Can someone assist to ensure this is looked into and practices are changed for future customers?
