No refund from Foschini

My sister and I purchased a series of treatments at the salon within Foschini. Then lockdown happened. We requested a refund within 6 mths of purchase. Were denied. We took the request to the TFG office. Submitted request for refund with proof of purchase. Was told there is no expiry date and we could go anytime. We requested a refund within 6 mths which falls within the credit protection and in addition, we no longer feel safe to go for any treatments that would mean having someone that close. Was told it was being looked at. Since then nothing. No responses to e.mail or messages to call. Not great service for customers of 30 years. Seriously unhappy.
