I felt a stomachache after taking it. Happens twice a, so just stopped it. The costumer service contacted me to propose what they call 鈥渨arranty happiness鈥 and see how they can fix the issue but the process I went through it was really disrespectful and more playing me even them who contacted me and offer to refund or replace which I refused then they insist with there message which was really disappointing and non professional at all. And just they insist to make more paying which was really indecent from them and I didn鈥檛 ask for or contacted them at all鈥 It鈥檚 one of the trust-worthless costumer service I experienced.
