Cancellation process is terrible and no one is helpful.

I has signed up with home connect in October 2020. Everything went well with their services, until I had to move out of my apartment and wanted to cancel their services. I made a call in September 2021 to cancel. The agent told me over the phone that this will be the final month they will bill me, it has been cancelled. They proceeded to bill be into the next coming year. I contacted them again in December and then they told me that I can only cancel online, I attempted to do it multiple times and still it was not approved. I called multiple agents, all have said they will take it up with the invoicing department (which by the way you cannot contact directly). I have since left my previous apartment in September 2021 and I am still being billed. I had to call my bank to let them know to block this debit order but they still manage to bill me every month. Every single month I reverse the debit order. I eventually managed to cancel it online but it is still pending. They still refuse to cancel my account/debit. It is extremely frustrating, that i have to deal with this eery single month. Every time I try to make a phone call and tell and agent what happened, they keep telling me that they will listen to the recordings and now all of a sudden they don't have any previous records. I literally had to scream and shout to get help and they still have not managed to assist me.
