Not refunding my card! Horrible customer service

On June 8th 2025 the billing department online was experiencing technical difficulties when trying to set up a payment. The page would not load automatic message popped up that they were working on the issue and it would be resolved soon. So I called in to the automated line to set up a payment arrangement for my past due amount of 80$ to be paid on or by June 15th. The automated system automatically chose the amount of 148$. And did not give me any other options. Within minutes i immediately called customer support to explain the issue. I was told don't worry you will not be charged the 148$ and that I would be charged the 80$ on June 15th. A day or so later they tried hitting my card for 148$ (payment didn't go thru)  I immediately called again to make sure they wouldn't try to hit my card again I was told don't worry they resolved the issue and turned off automatic payments and that I would have to call in on the 15th and make my payment of 80$. My service was then shut off I called they apologized turned it back on and the a day later they hit my card AGAIN for 148$ this time it went thru. I called again was told it would be refunded. A couple days after that my card was then charged the 80$ on June 15th  charging me a total of 228$. I have called several times spoke with someone for 30-45 minutes or longer explaining the whole situation every time I called which has been 10 times! there have been 4 tickets sent in to their payment department each time it takes 3-4 days and they decline the refund. I am infuriated and beyond frustrated. as I have called and spoken with someone MULTIPLE times even before the charge ever went thru to my card. How hard is it to refund me my 148$ that should have never been charged to my card to begin with. No one knows what [Edit: Language] their doing...clearly. Not to mention the language barrier every single time I call! Clearly No one speaks or understands English well enough to resolve an issue. Now I know why Xfinity has the worst reviews ever.
