Not giving Refund: Visa consulatancy services

I had approached Beyond Infinity which is a visa consultancy firm to obtain a job seeker's visa to Germany. I had paid the sum of Rs.30,000 + GST in the month of March. It has been more than 6 months now, but none of the process is initiated, i.e, no interview was scheduled with the German Consulate. There was absolutely zero progress overall and they are giving the reason for the delay as the Closure of Embassy due to the pandemic, because of which they are not able to schedule an appointment with the embassy. I had signed the agreement in which they have mentioned a few points wherein the refund policy is also mentioned. I do not satisfy any of those conditions which hold for the denial of a refund. They are claiming that they have given the services. the services they have provided, according to them, is their reply to very basic queries. How do I deal with this and get my refund?
