Phenom Health Company marketed 2 products in UK on trial basis which I bought for an affordable price of £3 each. Larnaca

The company, Phenom Health, marketed 2 health products in UK called Daily Power Cleanse and Wild Raspberry Ketone on a TRIAL BASIS. I purchased these products for an affordable price of around £3 each using my credit card and the payments were noted in my account on 26th November 2016.

However a month later without my knowledge or approval I was charged around £150 for the 2 products which were sent to me without my requesting them. I later e-mailed the UK office and telephoned them to state that I did not request the products and that I was fradulently charged on my credit card. I was informed that the amounts would be refunded when I sent the 2 products back which I did by post. I also received by e-mail on 13th February 2017 from the company separate e-mails headed 'RETURN MECRCHANDISE AUTHORIZATION' with separate reference numbers for each returned product.

I subsequently called the UK office and was asked to send a copy of my postal receipt as proof of return of the items. This I did immediately but have yet to be offered the promised refund . Now when I call the UK office number there is no reply at all.

Please can a suggest what I canm now do to obtain my monies 

Thanks you
