Need Confirmation that my cancellation request has been full-filled

I called on 7/30/26 to cancel my internet service effective 8/3.

I received two emails, one on 8/1 and the other on 8/2 saying "we've received your cancellation request, and we're on it", however, under the Cancellation Details, Last day of service is blank on both emails.

I am also waiting to see how this final bill is going to go. The "billing date" was July 21, for services from July 25 to August 24. Last day of service was to be 8/3, so I should only owe 10 days of usage in this cycle, yet the bill says I owe $50. Under the "Upcoming charges" the negative amount went from $38 down to $24 in a matter of days.

I could barely understand the rep on the phone, CAN AN ADMIN contact me to explain.
