I happened to visit al grissino in DIFC dubai, on 14th Feb 2017 as part of valentines plan as a employee who is their marketing manager invited me there. Subsequent to that I came back and edited my review on zomato and also didn't like the place and shared it on my Facebook. Which I took off from Facebook later. However, after this a couple of friends shared the same on the Facebook page.
Meanwhile my friends and I started getting threatening mesgs copy of the same hs been attached . Where in I was sent a mesgs that if I do not take the ratings off I will have to pay a heavy price.
Also my friends started getting fake mesgs from a profile named Ria Oberoi on Facebook who claimed to be a lawyer with Luthra and Luthra associates.
While my friends were getting the mesgs hey have logdged a police complaint against unknown person and the matter is under investigation by the chandigarh police.
Meanwhile Facebook has deactivated the profile after police complaint saying it contains abusive and threatening content.

It's a humble request that the matter to be taken up with the owners of al grissino dubai in order for them to take appropriate action against the marketing manager of that place.
I have already approached media houses and they are ready to take up the story however before doing that and making hue and cry about it I wanted to info the authorities in zomato. That as a customer it is my right to post a review and that's all I did. When I gave them 5* ratings they were happy but when I went there it was a sad place and I didn't like the behaviour of the staff.
I also know tha I was invited by the marketing manager and that person is dealing with zomato.
This is a serious offence of the activity that they are using fake and Fraud people to threaten me and others and thus I look forward to your reply and appropriate actions to be taken against the perpetrators of the said activity.
Copy of the mesgs has been attached for your reference.
