Titan Company — Product not delivered after payment has been made

I have made an online order of product named "Raga Viva Blue Metal Strap Watch" with ref no : NN2578SM01 through official app of titan company (World Of Titan) using UPI mode of payment bearing a transaction ID : T2112131015310464084840 dated 13/12/2021. I have even raised a complaint for the same through mail ([protected]@titan.co.in) and contacted their client through customer care service (Ph No: [protected]) but did not receive any response from their side. I ask them for either product delivery or refund for the same along with delay compensation.
