RCS unreliable

RCS credit card(general purpose account) I opened an account with them. There was a clause that says if I take the insurance on my account it will cover my credit in times of retrenchment. Me too being excited for this insurance I took it. Come covid 19 on March and by August I was retrenched at work. I called them and informed them about my current situation. They were reluctant to assist me. They doubted me that I was retrenched. They couldn't even believe the retrenchment letter I was showing them in goodwood office's. I was referred to certain email address to forward every relevant documents. I received a call from their head office asking me to forward my uif 19 as to prove that I'm jobless, which I did. All that was in vain because they kept on calling me reminding me of my credit why I didn't pay but they knew my situation. The moment department of labor paid my uif I had to settle the account and close it. Now what happened to my insurance which they were deducting monthly. I'm very disappointed in RCS they don't keep their word and Luyanda from insurance department called me and promise to refund my insurance as they didn't fulfill their promises. He just disappear in thin air as well, after calling them numerous times.
