ZYYMHM review: Order via Instagram

I ordered some item's via Instagram that I thought was from River Island at a cost of £39.99 in October, I have emailed and had tracked this and keep being told that it is in Transit and due to the delay a 60% refund will be given, we are now into December and I havent heard anything or received the refund, I got home yesterday to a package of a Ring (cheap and tacky ) from this company which I havent ordered and wouldnt order as it is horrid, Please can somebody let me know why and who this is as I am worried that they have scammed me as they have got my bank details

Look forward to hearing from you soon
