Pepperfry — Product not delivered for almost 2 months

I bought furniture through pepperfry.Com, they promised to deliver it on 19-aug-21. But the product was not delivered and there is no communication on shipping, tracking. I have called up several times to their customer care they told a revised date of delivery. This was repeated many times but the product was not delivered till date. Requested for a refund that also not processed. Fed up contacting them as pepperfry grienvance team also not acknowledging my mails or queries. There is no escalation further they said and have not done any action against the complaint. Product not delivered and refund also not paid
