Unresolved issues with Seasonal Convenience Plan

Hello, I'm reaching out regarding an ongoing issue with my seasonal convenience plan, it was never resolved through the live chat service nor via phone with customer care. In all previous conversations with customer support and live chat, I was assured they would adjust my seasonal convenience plan billing.  My seasonal plan that included limited internet became effective from 10/29/2025 to 3/26/2026, on 12/1/2025 I contacted tech support because I had no services, not even the limited internet.  On 12/1/2025 the Chat agent in error reactivated my services instead of sending a new signal to allow the limited internet.  I received an email informing me that services were restored and I immediately rejoined chat and actually spoke to the same agent who reactivated the seasonal plan, I received another email confirmation on 12/1/2025 stating seasonal plan was updated to March 26, 2026.  I have now received my monthly bill and it includes charges for my regular monthly charges instead of the seasonal even though when I log in and review my season plan order it states the original dates.  I have since spoken to customer service via phone who stated the issue would be resolved and I would receive a credit and proper billing going forward to end of the seasonal plan date, however the specified time for the credit to be appllied has since passed.   Despite multiple attempts via live chat, the problem persists, and promised email confirmations never arrived. Can someone please assist me with this matter?

Thank you
