Xpressary Order never received...Neoprene Sauna Waist Trainer Los Angeles CA

I ordered and paid for this product on Feb 26, never received a tracking number.  First email I sent was March 12, response I received was that I would receive my order in three more weeks and they would credit my shipping of $4.95. 

Again on April 11 I emailed that I still had not received my order or any tracking info, they responded that now the item was on back order and they would refund me 20% of the purchase price and ship as soon as available and they would provide tracking info.

On April 26th I again emailed that I had not received and they responded saying they had confirmation that the product shipped, still no tracking info, but that I would receive in 1-2 weeks, from Shad in customer service.

Yesterday May 11 I emailed again, stating I no longer wanted the product, that another two weeks had come and gone and I wanted a refund of all my money.  They are now not responding at all, and this is almost three months to ship a tank top!
