Excellent product, terrible response from this distributor(Aggressive Health Shop). I ordered a product(vimergy b-12) and I paid extra for next day delivery. I had to waste precious hours and hours, day after day of my time chasing this delivery so it can finally happen a week later. I asked for a refund on the additional amount I had to pay for next day delivery, as this never happened. I got completely ignored and didn't receive this refund. As I can't rely from this distributor for Vimergy products, I have to purchase from another distributor in Europe. Shame that a middleman(distributor) could potentially destroy an excellent product.
