Should I settle for a refund of Rs 40,000 less?

An immigration agency took Rs 121600 (Rs 3600 for technical round, Rs 10000 for counselling round, Rs 108000 including 18 percent GST for PR services) from me. They lied to me regarding proof of funds and job promise in the beginning. After paying complete fee, I found out I have to arrange proof of funds myself. I asked for refundThey are refunding Rs 82,000. Their logic is that the technical round of Rs 3,600 and the counselling round of Rs 10,000 have already been conducted (I did avail these services from them) . Apart from that Rs 19,440 (18 percent of Rs 108,000 ) went to GST. Some of the money went to lawyer making legal agreement which they sent to me to sign and I did not signDo you think I should accept Rs 82,000? (I have already sent them legal notice after which they are offering me this amount)(They had lied regarding proof of funds in the beginning and also about job arrangement).
