Ajio — Item not delivered, courier company not contactable, Ajio not responding

I purchased a shoe from Ajio on 6th October that was to be delivered within 4-5 days. on 11th October suddenly the status of the delivery shows as delivered. We kept contacting them saying we have not received the item, The content number shared of the courier company is never reachable (+[protected]. The emails sent to the courier company remains unanswered. WE raised a complaint with Ajio on 11th October after multiple attempts of reaching them and they promised a resolution by 18th October. On 19th October, after not hearing back from them, I called and was told the agent had noted incorrect complaint and to give them time till 25th October. The agent then hung up on us. Their lines constantly have log hold time and if we get connected, the agent hangs up. We have paid Rs ₹5419.57 and received no product, no support and no proper response.
