Cache mercantile fraud company

On 8.12 I was called by one sachin in my mobile and offered medical health care , thirocare , dental care recovery based facility and hotel etc free boking etc on rs 6990 . I trusted them and allowed to paid from my sbi credit card . On receipt of the CC bill from sbi I contacted on the above number and they told that they will reply within 10 mins , which never came . On my search in the internet I came to know that the company isa fraud . Kindly take appropriate action and recover my hard earned money . I am a senior citizen . Pl look into it . Thaanks
