Extra Disney+ subscription added without my request

Dstv decided to unilaterally add a subscription to my account without my request and have the audicity to debit my account. This is the most unprincipled thing ever. It cannot be done. If they feel that they want to add subscriptions to my account, they must pay for those subscriptions. Please refund the Disney+ subscription fee that you just debited. Don't ever load anything extra on my account and expect me to pay for it.
