Google play vouchers purchased that don't work, not refunded as promised

I feel exceptionally disappointed with the service received from the Absa rewards division. As a client for over 30 years the service received is appalling.

I purchased 2 Google play vouchers on 21 February to the value of R1 500. The vouchers do not work. Due to ill health I only called into the rewards division on 8 May and was advised by the consultant that request was logged and I would receive a refund into my cheque account by 10 May. I gave Absa 9 days to refund the money and still no deposit was reflected in my cheque account. On 16 May I called in and was told by the consultant that he can see the request was logged and that he would escalate to the rewards manager & that I would receive my refund by the end of day. Well it's 2 days later and no response.

Reference number C-*** refers

I truly hope this matter is resolved. Poor service is unacceptable.

Many thanks
