Amazon review: Blouse

I ordered a blouse on Sept. 1. The original delivery date was Sept. 10-12. Amazon tracking says the carrier (Newlogistics) picked it Sept. 5. But when I checked with Newlogistics they showed they never received it. After Sept. 12 date passed, the new delivery date was changed to Sept. 16. That passed and changed to Sept. 21. I have not received my item and contacted the seller. They replied the delivery date had not passed yet, so they could not do anything. I next called Amazon customer service for a refund. They said they could not get me a refund because the Sept. 21 delivery date had not passed and they would contact the company (Woman Within) and wait for a reply for 48 hours even though I had previously contacted the seller through Amazon. It is ridiculous that a company can keep changing the delivery date and prevent you from asking for a refund. I don't ordinarily complain on public forums. For example, back in February I ordered yoga pants and received a white blouse instead. My son was in the hospital for over a month. I asked for a sticker by mail from Amazon to return it, but never received it. By the time I got around to requesting a refund, just over 30 days had passed. I didn't make a big deal out of it and just let it slide. When I have ordered items from Amazon itself, I don't have problems. But I will be sure to check who the shipper is and what company I am dealing with before I order again.
