Safe Harbour Informatics interview questions

Such a Fraud company. Friends please do not trust them, I recently had a interview with them along with their client. They will not release your offer letter. I was waited for two months and there is no response from them(Not answering our call or messages). I already declined two of my offer from most trusted and well known organisation and sitting idle in home because of this frauds, they said they will provide me WFH option and expected salary but nothing was happened. Guys please be aware of these kind of companies and better not to respond them. I blindly believed them and that was my biggest mistake and I am still regretting.
