Cancellation nightmare

Cancelling your contract is a nightmare. My contract is ending soon (29 September 2026) I sent a cancellation request to the early cancellations department on the 28th of August 2026, informing them that after my contract expires, I do not wish to continue on a month-to-month basis, I would like to terminate my contract when it's expiring on the 29th. So far, I've tried sending emails, I've tried to chat on whatsapp, I've been calling them just to be transferred from one agent to the next, all I want to know is if my cancellation request was processed, it certainly can't be that difficult to check.
