Yourll refuse to cancel my month to month for months because you need proof of delivery from an order from year ago. I feel abused

I have a 5g home internet plan since Jan 2025. In October I got a vodacom one and wanted to cancel the mtn.

I attempted to cancel about a month ago and it was a disaster. I went to the store and they said I need to get proof of dsv delivering the router to me know. Order to return the router and cancel. I sat in the store for 30 minutes as I wanted it canceled but to the same ending, I still have the contract.

Im currently paying for my vodacom one and this mtn one, so its unrcesswry and so hard to cancel

They said they sent for proof of delivery from dsv with their customer service. When I called today there's nothing and still can't return the router and cancel.

I stopped paying the mtn bill as I have 2 contracts and its like yourll dont want your router back.

Why is there so many blockers and I demand for yourll to cancel this and I can return the router. I also dont want to pay the balance because this was supposed to be sorted by now.

I feel abused . Its a month to month deal, so there's no reason that we shoild cancel

Ps I visited the gateway branch
