Refusal to cancel contract

They refuse to cancel my contract even though I have fulfilled my 12 month contract. I initiated my notification in April I was told they are under lockdown restrictions they can't process my cancellation I must wait till end July when my contract ends. Which I did and even gave them a grace period till lockdown level 2 (18 August). Now they are stating that because they reduced payments for all clients for 3 months we have to pay them: 1. I didn't consent to the payment reduction (they did that to save their client base) 2. When I did my initial cancellation why didn't they mention they would be extending people's contracts (which is ******** as I didn't consent also) they failed to give their customers options to continue fully paying their monthly fee or deducted fee which comes with contract extension

I've opted to go to the consumer goods and services ombudsman. It takes time to build a reputation and sadly Fight Club opted to destroy it over a few rands. My family, friends and I will definitely not be supporting them in future. And hopefully, those reading this won't want this headache.
