I ordered two gold 21Karats items from Rasha (one ring and one bracelet) on 21MAR21, she requested $150 on the ring and $275 on the bracelet, and she asked for $25 for shipping. total was $450. I paid using zelle to the number 773-961-6216. She sent me a tracking number on 23MAR21, and the items were delivered to Missouri on 27MAR21. Once I opened the mail, she had the receipt without the number of grams of gold per piece as all gold jewelry stores do. She took $25 for shipping however, the USPS shipping was $4.30. I thought she would send it with UPS or FEDEX. However, I told her that I am overweight and the items are small, I requested a size 9 ring but what she sent did not enter my fingers. the bracelet was small and very thin and light for the price. I asked if she can replace them with something with $425 total and she said no, the items price will go down.  She has a 14 day online return policy and we are in the US not in Iraq,

stealing people money is not a good moral character for an American citizen. she blocked me from the facebook so she does not return any item or replace or refund. I reported her to the community facebook ladies group and most ladies in the facebook group mentioned that this business is dishonest and sell fake items. No my gold items do not have a stamp or anything to indicate they are 21K gold. I am requesting that I return items and a refund of $445.7 to my account after I return the items to them. I will only pay for the $4.30 USPS shipping that she paid. I looked into the google and yep reviews after I purchased and they are all negative reviews. I have to report this business in order for other people do not fall in the same trap I did fall into. I appreciate your support.
