Current technology india limited kolkata electronic wala - Package not delivered nor amount refunded

I saw there ad for ps* pro on olx and they shared there whatsapp business account number. They asked me to pay ***** then they asked to pay **** more for GST and delivery charges. Payment was done on Gpay numbers they shared. I communicated with Aditya from current technology. Then they told me that they mistakenly shared wrong number and amount went to someone else. They never picked my calls or responded to my msg. After almost a month aditya again contacted me saying he will give me new ps* if i pay him **** more. Saying his company does not have any refund policy and won't return my *****. They are such a big cheater. I have filled complaint against them on national consumer helpline and on cyber crime even if i dont get my money i will try they are not able to cheat anyone else in future.
