4 months ago i signed up for a free trial for acia berry tablets (order no.102075983)which should have cost $2.95 for shipping. Since then i have been charged by 4 different companies each ampont around the $120.00 for which i have not recieved anything from, only 3 lots of diet tablets which i did return. I have found it very hard to find any contact details to stop this from continuing. I would like to be refunded of these charges they have taken from my credit card.How can i get refunded for this? Please help
