DigitalIndiaTechSolution — Neither payment nor refund of fine amount received

Address:	New Delhi
Website:	digitalindiatechsolution.net

I got a call from [protected] on 11th june 2020 from a company named digitalindiatechsolution providing a data entry job by working at home. The job was to fill 700 forms in 6 days, which if i don't complete then i have to pay penalty (As per the agreement). They didn't ask any registration fees just an id proof & email id, and i gave them. Then i received an email for account activation which had an agreement along with it (Which i have attached below for reference). Since they didn't ask for any registration fee i signed the agreement and started the job using the user id and password which they sent me through the mail and sms for my data entry job. On the 16th of june, the last day to submit all the forms when i had just two more forms to complete the webpage showed some error and i immediately texted the one who called me the first day. She said the technical team will contact me and yes they did call me (No: [protected] and [protected]) and told me that i was not able to complete the rest of the forms because of some mistake i did while entering the data (Like pressing the enter button without filling the entire form) and that i should pay a number of rs.3999 as fine so that i can get the new user id and password to fill the rest of the two forms. I did pay them and was told that fine would be refunded after my salary was paid. I completed the work and texted them and was told the company will call me the next day but they didn't. Thereafter they have not been responding to my texts and their phones are switched off. I just want my refund of the fine which i payed. Please help me. The bank details which they provided me to pay my fine is mentioned below.
