Repayment and cancellation

I became unemployed, then I tried contacting Clientele so that I can cancel this policy, after many attempts trying to get an agent to assist me with this I finally reached one. On the call I explained my situation to the agent, his name is Bongmusa. He told me that at Clientele they have a Holiday something I forgot what he called it, he said they will give me 3 months, in the 3 months I won't be paying until I get another job then continue paying once I got the job within that 3 months. If I haven't been employed within that 3 months o can then cancel, I agreed which was my worst decision. I did not receive any email or sms from them about the holiday thing. Next month I was debited twice. When I try contacting Clientele again the line is always busy, even their WhatsApp is not transferring me to an agent. I would like them to pay me back my money and to cancel the policy ASAP. I do not want to be part of them anymore.
