nutra life brands Garcinia cambogia slim free trial turned into not so free tampa fl Internet

 I went online to get my free trial of garcinia cambogia slim and paid 4.95$ shipping and handling, I only wanted that one bottle and now they continue to charge my account for more and more money when I did not authorize a re accruing card purchase. I've called the number and left several messages and never get a return phone call. I've also sent emails after emails to them requesting my money back in return for the un opened bottles. I am a single mother and now my account is 56$ in the negative and I cannot afford for this to keep happening. Please help me.
