SOTC — Visa fee refund

We (me and my wife)had taken SOTCs European Splendour tour from 19th Sept to 30th Sept 2023. We were assured that we will b bearing the cost of visa. When we went for visas we were told that you pay the fees right now, we will refund once visas will be issued.
Two months have been passed since we boarded the tour they have not refunded my amount₹ 16, 475/- despite so many requests at their Rajkot office. The branch manager keeps on telling that its in the pipeline. But how long shall I have to wait? My account is clear and I was told that once I complete the tour I'll get refund. Pl take up my case
