Lupin Pharmaceuticals review: chemicals 9

I was looking for 2 kinds of chemicals through Indiamart e-commmerce platform so I found out that Lupin pharmaceutica Ltd was the leading supplier for thes chemicals. I contacted this supplier and from this moment on I had email correspondence with Lupin Phamaceuticals Limited - Sales & Marketing Manager.
After some trade negotiation we agreed on a purchase price of about 400 USD.
I was mede given these data for the payment trough Western Union:

FIRST NAME : SAMUIEL

LAST NAME :WALTERS

Address : B/4, Laxmi Towers, Bandra Kurla Complex India

Country : India

As soon as I made the payment, he disappeared.
I contacted [protected]@indiamart.com and this is their reply:
"We highly regret the inconvenience caused to you.

This is to inform you that the said supplier is already disabled with us under negative tag due to a past complaint.

Now, we request you to proceed further at your end only."
In conclusion I have no hope to be refunded.
I have been frauded by this so called Samuiel Walthers.
I think he used fraudolent documents to mislead Western Union because the adress he gave me (B/4, Laxmi Towers, Bandra Kurla Complex India) is the real adress of the Lupin Pharmaceutical Ltd, Mumbai.
If he was really the Sales & Marketing Manager of this company, he surely wouldn't frauded me.
