Worst service by Wi5. Review on Wi5 - Wireless Broadband

I have been Wi5 broadband in Chennai for the past few months. The service is completely shutdown from 31/5/13, we tried calling the customer care phone number 1800 3000 0555 mentioned on the website but no response , tried sending email mentioned in website but there is no response. Tried visiting the T.Nagar office mentioned in the website but there is no such location currently they have removed the address in the website. I have incurred huge loss without internet and also they have taken the money. I hope others also are suffering from this problem. Finally I called the number 91 44 3915 7000 mentioned in Zylog website and the person picked up after 3 days but he said wi5 is seperate but I fought with him that Wi5 and Zylog belong to the same group and you are responsible and he agreed gave the number of the customer care manager 9380994597, I also tried calling the manager number but there is simply no response he disconnecting the call. Is this a genuine company? where is our money? where is the service? All guys please join as a team and let's fight to get our money back.
