Is This Not Breach Of Contract?

Location: Georgia. I’m currently active duty Army and had Xfinity mobile in the U.S. the bill was fine in the states and was per usual (I have unlimited data btw). My unit ended up getting sent across seas to Europe for rotation and I started using google fi while over there. We went to JMRC (Germany) for training and google fi wasn’t working there at all. So I started using the “global travel pass” ($10 a day for this pass) with Xfinity since Germany was a valid global travel pass place. In the global travel pass it says “you pay $10 a day for the full 24hr pass”. So if you bought it 2pm May 23rd, your pass would expire May 24th at 1:59pm. We finished training in Germany and were otw back to where we were temporarily stationed. I called Xfinity to cancel the travel pass (after canceling online as well) to make sure it was CANCELLED thoroughly. Within FOUR MINUTES, I was charged $5,000+ to my account… yes that was read correctly. (Also yes my data roaming was off for that phone number and the data line itself was off and paused through Xfinity. Even if it wasn’t though, $5,000 in under 4 minutes is impossible.) While on deployment I spent 2-8hrs on call with multiple Xfinity associates because I would have calls be 6hrs long and an associate would hang up in my face. I had to argue and fight Xfinity for 4 1/2 months before they realized they were in the wrong and credited my account. Those 4 1/2 months I spoke to at-least 100+ agents/associates. Half told me “I’m so sorry about this your account will be credited after our back end team reviews the ticket” and the other half tried to tell me it was my fault and that the charges were valid and told me if I didn’t pay id be handed over to the collections office WHILE having MULTIPLE tickets open for this issue. I even spoke to a tier 3 retention associate and still got NO assistance or credit. After 4 1/2 months they finally admitted they were wrong and accredited the account and then tried to make me pay the late fees from those 4 1/2 months I didn’t pay the $5,000+ bill. (I was told not to pay it by my leadership because I would be legally responsible for the bill, and even if they didn’t tell me to not pay it I sure wasn’t paying it anyway). And I couldn’t pay my regular monthly phone payment unless I bypassed the $5,000 bill. Which they’re also trying to make me pay. They won’t compensate me for my time and wipe the money due on the account which is $350+ in late fees and 1-2 months of my regular phone bill (my phone bill is $60 just so you can put into perspective the amount of late fees stacked and fees I was charged for an “outstanding balance”). This happened during the end of April/beginning of May. I’m still fighting this to this current date. Is this not a breach of contract since I agreed to the terms and conditions of the new agreement involving the global travel pass and it states in the global travel pass on their website about not being charged until the 24hrs is over and I was still charged within my 24hrs PAID pass? Or am I just overreacting?
