Wish complaint: Lack of refund (received nothing)

I ordered 10 items, and I did not receive any of them. I had to request a refund for each item separately, and they refunded some of the items. But then when I went to get refunds on the remaining items, they have flagged me as abusing their refund policy. I appealed it, but I have heard nothing and they’ve had ample time. They owe me the balance of what I have already paid. Also, they do not refund shipping. This is unfair. I want a refund for the entire amount. It was never shipped. I can prove this because they sent me emails about the shoes not being able to fulfill the order. The shipping refund responsibility is theirs and not mine. I cannot reach a human and my emailed go ignored. They send out automated emails stating that they are reviewing it. And lastly, I want it noted that they only give you a 30 day window to get refund, so I feel like they are “running the clock” so speak so that they do not have to refund this. It really is not fair.
