complain from muslim student regarding "Subway".

Question

Salam I am a muslim student and I often eat outside. I seriously do not understand which restaurants are really halal or not. Nowadays there is no law which restricts a restaurant on the issue of halal and haram. I went to Subway last week. I saw there was a halal logo on their flyers and halal posters stick to the wall. I found that really strange since I personally know that their products come from chicken Master and Fast food ltd which main suppliers for pigs on the island. When queried about the halal certificate, i was shock to see a certificate from Jumah Masjid awarded to Fresh and ready which are not their true suppliers. Moreover the certificate is a copy and it’s clearly written on that paper that a copy of this certificate is not valid. I asked the girl who fortunately is a muslim and then I learned they are forced by their employer to present this to customers. How can we remain idle to such a situation? Our Muslim sister is being forced to lie. Can't your organization do anything?
