The Shopping Bazar — prepaid order is not delivered yet and they are not even answering

Hi sir/ma'm
So, i ordered one saree from a fb link, i mailed them to ask them there return policies. They replied the mail. Aftr that i order that saree on 31 aug 2019, the order no is 41567 and cash on delivery option was not available on it so i prepaid it. They called me to confirm the order and said that the order will be deliverd by 12 sep 2019. There is no tracking service available on their site. I mailed them so many times and they are not reverting back. The mobile no is switched off. Yesterday i again ordered the same saree from their site to check whether they will call back to confirm the order and this tym cash on delivery option was available and they confirmed the order by mail only and hvnt called till now.. Kindly do the needful
