OYO — Oyo refused to pay GST Invoice

I made a hotel booking through OYO and made entire payment which was inclusive of GST tax. When asked for gst invoice, they aksed me about my GST details but being a student having no company, I don't have any GSTIN number and when I tried to explain this to them all they told me was that they won't provide me GST invoice in that case.
I clarified this with CBIC helpline and they explained that any supplier charging GST from customer will have to provide GST invoice when asked for. If the supplier doesn't provide then it is considered a fraud.
OYO has time and again proved to be a fraud company, doing nothing but disappointing customers.
I have had pathetic experience where I have literally made 10 calls a day to OYO helpline and they just kept delaying and ignoring my request.
