Adda247 Online Course Providing Institute — purchased online course but not provided to me

Website:

www.adda247.com

I gave a missed call to the number given by them inorder to activate the ssc cgl course (1hr offer). They sent me payment link to my mobile number. Payment was done via google pay but order is not placed. Contacted and mailed them multiple times but nothing in progress. After sending mail they gave a ticket id inorder to register a complaint. I registered that also and had a chat with customer service but they're way too lazy to answer my questions. They are deleting my chat and keeping whatever they want. It's been more than 7 days but they are not providing either the refund or the order. Tommorow the course starts.
Paid rs 1498 via google pay
