Zando and Fox Racing order #***

I purchased items on the Fox Racing website which is then facilitated by Zando. What swayed me in purchasing this product is the fact that I was granted a R200 voucher for my first purchase. Accordingly I utilised the voucher and placed my order for a specific event based on standard delivery timeframes. 4 business days later i am informed via Zando that both items are out of stock and that I've been given a voucher to choose something else on the site. The correspondence which has followed has been sporadic with days now passing without responses to my emails. At this stage, my time has been thoroughly wasted, I have not been able to order something for the specific event due to the lack of answers to my questions, I have not even been given an option for a refund and as a final kick in the teeth, the vouchers received are for an amount net of the R200 discount (for a first time buyer) which I have obviously never benefited from and cannot use again. You should be incentivising your customers to return, at the very least returning them to the same status when they placed the order, and not prejudicing them when you as the service provider can not fulfill orders.
