Cancelled service, paid final bill already, why is Telus still sending me an e-bill?

I had cancelled my Telus home service three months ago, and after that, returned my modem to them, and Telus e-billed me for my final payment in January 2026, which is 213 dollars.  In February 2026, the e-bill came again, and the statement was 0.00. In March, Telus didn't send me an email. I thought it was perfect; no more bills to pay. But now in April, Telus sent me another E-bill again, and I owe them money,  but when I log into Telus, the home service account doesn't even exist anymore. Do I need to pay, or is it a system issue that they charge me incorrectly and still think my account is still in use?  Please have Telus send your support team and message me.
