TB Dress Company will not refund my money Suzhou Jiangsu Province

I ordered a dress for wedding that was to small due to their measurements being much smaller than described. Once the dress arrived I realized it was to small and contacted TB Dress. The company was willing to offer a refund if I ordered another dress and show them proof of the order which I complied with their requirements. Once I showed proof of new order I received the address for the return. I received dress on April 5 notified company of dress being to small shipped dress back on 4/10/2020.  

I paid $75 to have dressed shipped back to company. This process started 2/4/2020 with dress being ordered, received and return to them by June 5, 2020. Company report dress was returned with a smell and had to be destroyed offering me a refund of $79 but later agreed to $129 with refund now expected by end of year. I had another item ordered I didn't receive nor was refunded.
