Vitality mall ******* voucher expiry

Discovery vitality mall sells vouchers with a 30 day expiry. This is ******* according to the CPA. After waiting 45 min on the chat, Nosi says she is the expert and clearly the legal representative who refuses to escalate my complaint that it should be valid for 3 years in accordance with the law of the country we live in. The wait time is unacceptable then to top it all discovery forgot to train in customer service.
