****mers and unprofessional

I am really frustrated about this dstv thing,my husband was on a 24months contract price lock with explora thing of which it ended on March 2025, now to our surprise they extended the contract without his consent and billed him foe the month of April and he called them in the month of March to tell them that he doesn't want to continue with the contract,we took two internet routers early this year now they have blocked them and no one wants to assist him and account for the mistakes they have made from their side. I need someone to follow up on this matter asap.
