company credibility check

Hello,

I'm keen to purchase some samples from a company based in India, the only company which offers PayPal as payment method for the goods I'm looking for. The selling lead was found on Tradekey, after reading this forum I realised this is highly risky, I've tried to Google the company and the contact I've been in touch with, but can't seem to find anything on them. What should I do? is there any way for buyers to check credibility of sellers online at all?

Here's the name of the company and the contact

Mohammad Faizal
(M.S) Mesco Sam International, India
Contact no: +91- 9808986080 / 9808230639

PayPal account: purchaseonline.intms@live.com

Grateful if you can get in touch with me if you have any info or have dealt with them previously, thanks in advance

Katie
