worst service ever

I called on the 21st August 2019 to cancel both my router and cell phone contract and I was told it will be cancelled on the 21st of September 2019. About 3 months later I realised the debits are still going through my account and only the router was canceled, so called in January to have the matter resolved. I was then told that the error will be rectified and the 3months debited will be re-embursed, till this day none of the above was done and when I call i'm pushed from pillar to post.
