No Accountability

I am extremely disappointed in the service received from Edgars and CNA. I bought a voucher in Dec '19 from CNA when it still belonged to Edcon. The voucher never worked and when I tried to get a refund, I have only had the run around. CNA told me to claim from Edcon and Edgars in turn told me they can't take responsibility as they don't own CNA anymore. Now I've been told by CNA that they can only reimburse me when they have the cash in store. 3 months down they have not been able to make up the R1000 they owe me. I suspect they think I'll write it off? Customer care has become non-existent and we are bearing the brunt for their business failure!
