BAD SERVICE ON CANCELLATIONS!

Submitted an cancellation request on the 12 of July 2021 already. Called in and was advised to send an email. Did this. Got an automated email back said that someone will contact me to confirm cancellation. 4 Weeks later still waiting on there reply. Contacted the call center on Thursday 5th of August 2021. Waited 25 minutes on the line, NO ANSWER. How do I cancel my LTE package???? Won't recommend this ISP to anyone.
