"This company is full of scam"

This company is full of scam. I received calls and whatsapp messages from their accounts manager called Mohammad. He called to threaten me since I didn’t respond to him message. I normally don’t respond to cold calls as I received many of them on daily basis. But this person does not have communication etiquette or the right behavior to approach clients. Plus he is calling at the wrong time.

So I totally don’t recommend dealing with this company or any of similar. They are all scammers
