No Ethics, Doesn't comply with their own T&C

I ordered a smart watch from Avon in November. Early in December I was informed by three sales rep that they are out of stock. I requested a refund, which according to their website should take 10 days. Fast forward 9 weeks and I still have not received my refund. The sales rep has been following up with her sales leader for weeks no and still no joy. Will I be refunded the R700 plus 9 weeks worth of interest... I doubt it. I will NEVER EVER order anything from Avon again. Their lack of ethics and communication is disgusting.
