Shapermint review: I want a full refund because purchasing from this company has been a complete nightmare!

I made a purchase from this company totaling $55 and through their tracking service my products were marked delivered. Well, I did not receive them and I have been trying to get a hold of somebody by text email phone and Facebook to try and get this resolved, and nobody has resolved it for me. It has been three weeks since my product was supposedly delivered and I did not receive it and I am a single mom of two kids who works really hard for her money and I don't appreciate having my money stolen from me like this. Thanks for nothing!
