I want my money back NOT store credit

I placed my order and it went through as a sale, days went by and while it was processed, I received an email stating that one of my items were out of stock and I have received a voucher with store credit. Now how was I able to purchase my item in the first place if it was out of stock? I emailed and called ZANDO multiple times, trying to state that I do not want store credit. I want my money back. I even emailed them stating that I’d patiently wait for my item to be restocked, but now with this lack of communication, I’m not too sure about that either. The fact that they didn’t give me a choice to choose whether I want store credit or my money back is just a slap in the face, the lack of communication between customers and ZANDO is appalling. I hope this review will help others make better choices when shopping online at ZANDO and I hope to get a prompt response from the ZANDO team.
