Droidso.com Ordered coat based on ad sizing chart, refused to replace or refund Internet

Ordered a Mens All-Terrain Tacdticle Jacket from Droidso.com (Fox Digital).  Jacket arrived but wrong size to what was indicated on sizing chart of order form.  Reviewed website and was instructed to contact sherrlajunen@gmail.com for return/refund information.  Ad stated ("30-Day Satisfaction Guarantee").  the contact (sherrlajunen@gmail.com) requested pictures.  I replied with request for replacement (larger size).  the contact (sherrlajunen@gmail.com) indicated that it would be too expensive to return and offered a 20% refund or 50% off the next ordered item.....basically to "go pound sand".  I repeated my request and offered to accept a full refund.  As before, sherrlajunen@gmail.com indicated that it would be too expensive to return and once again offered a 20% refund or 50% off the next ordered item.  Do not do business with this fraud.  She/he/it are unworthy of your regard.
