Do not respond to issues and then expire points

I have always had good experience with Enlighten. However, there was a time when we were redeeming vouchers and not getting them or getting used vouchers and nobody was responding to enquiries. Now I have the exact same problem with their referral site, Switched On.

Just like others here, I joined Switched-On some time back. Although I have managed to redeem vouchers, I had an issue with using the takealot vouchers. It kept coming up with an error on their site. I sent a query through the website at the end of March and still no response has been received from Switched-On from that channel. I was waiting on this problem to be resolved before redeeming more vouchers. I figured there's no point in sitting with more vouchers I cannot use but nobody was assisting. Now I have the same issue that without warning my points have expired. Sent an email this time enquiring about the points expiry at the beginning of this June about this being unfair. They do not communicate and the expiry information on the website is not accurate as I checked this frequently. Anyone able to assist with returning my points? I did get assistance via Freejoy but this was only in terms of the takealot voucher. Others are complaining as well so I am definitely not alone.
