Loan extended

I took a loan with Capitec Bank in October 2019. I agreed with Capitec to certain terms and conditions. Some of those were the repayment amount and repayment term.

On the 4th of June I received an sms telling me that my loan term will be extended.

When I called Capitec I was not assisted instead I was told that everyone's term has been extended due to the added risk caused by COVID-19, and that some people might lose their jobs and not be able to pay.

I asked the consultant why are they making assumptions and why was the agreement changed without my consent and without any communication with me. I didn't get any answers nor help. Why was my contract changed unilaterally? Why is Capitec assuming that anything has changed on my side? If they want to change anything on the contract why are they not reviewing their interest rates?

I'm not happy with the service and ******** conduct of this organization.
