Shine.com — Cancel My Subscription which I have not used and Initiate Refund

On 14th July' 21, I got a call from an executive from shine.com ( HT Media Group ) for paid services and I paid Rs 3292/- ( IN20210714_516051 ) and the executive said that I will get a call from senior manager for more update . And I got a call on 15th July'21 and they extracted Rs 4673/- ( IN20210715_516737 )
(for Education Verification Plus Package ) further they extracted Rs7197/- ( IN20210715_516747 ) ( for Job Profile Verification Plus Package 2 ) afterword they extracted Rs 12978/- ( IN20210715_[protected]_[protected] ) ( Career Assessment Test with Expert Counselling ) and later on they said one more payment I have to make of Rs 18407/- for which I denied . They all are trained professionals who will not reveal total how much you have to pay .Slowly slowly and step by step they will say you to pay the charges and each time the charges will go on increasing . At one go they will not say that you have to pay a certain amount which can cost you more that 30k or 40k .They will say that as per your requirement and experience you will be charged . They all are well trained to cheat people in the name of job opportunities .
So after making payment a total of Rs 24848/- which I paid on 15th july'21 immediately within 30 minutes I mailed them for cancellation . But the bluntly denied for refund .I have not used there services at all so I need my Full Refund ( 24848 + 3292 = 28140/- )
